Can we get consensus on what incubation means (was: Re: WICG Incubation vs CSSWG Process)

My apologies for not participating in this thread sooner (but, in my
defense - holiday hiatus).  Retitled as per Fantasai's suggestion.  A few

   1. I think Daniel's definition of incubation had the right core: Incubation
   enables exploration of ideas to a stage where they are an interesting
   enough and mature enough proposal to become a stated deliverable for a WG
   (i.e., an Editor's Draft and then Working Draft on the REC track of the
   Working Group).
   2. However, there's a key feature that is missing there, that I went
   into at some length at TPAC - incubation has to enable graceful failure.
   By that, I mean that ideas that are being incubation don't have a timeframe
   for completion, nor is there any penalty if an idea goes back on the shelf
   (or dies completely) - and in particular, *it's clear when that happens.*
   For example, the CSS WG charter <https://www.w3.org/Style/2016/css-2016>
   has a large number (29, I think) of features that are "Exploring".  The CSS
   WG *has* been incubating ideas for about 20 years (although for the first
   couple of years, to be frank, we were just slamming most of the ideas
   straight into the specs, since there was a lot of blank ground) - but the
   scale has gotten a bit out of hand, and yes, the explicit "incubation" is
   partly about getting more externals involved.
   3. As for the commentary on scroll-anchoring, et al - yeah, there are
   always rough edges, and vendors will not always follow your best
   practices <https://www.w3.org/TR/CSS/#future-proofing> on future
   proofing, when there are critical user functions to address.  However, I
   will call your attention to Rick Byers' explicit comment in that issue
   "The actual API surface area is tiny and rarely needed, so I'm optimistic
   we can continue to incubate,* including making breaking changes if it
   becomes necessary to get interop in the future*."  (Underline is mine.)
    If we ship features before REC, we are responsible for maintaining.
   4. I'm not sure where the assertion that this [early/"premature"/"sans
   REC"/"unstable" feature shipping] doesn't happen was made; I certainly
   wouldn't have said it.  It will happen.  It has always happened.  This
   needs to be managed, and minimized as possible, but I don't believe it can
   be avoided - and so I want to make sure we clearly define it, and make sure
   implementers understand their responsibilities.
   5. Fantasai, you stated "Furthermore, many WICG people seem to think the
   spec should be 'done', aside from minor details, when they're done with it,
   and the WGs shouldn't be involved in any actual spec development work."
    I'm not sure who those "many WICG people" are - to put it on the record, I
   believe this will sometimes be pretty true, and many times not be true.
   6. You've made a case for the "WG's broader expertise" not being applied
   in an incubation process because "In practice, the people working on
   something in the WICG (or in any other limited-audience 'incubation' group)
   are a subset of the people who would pay attention to it once it's
   transitioned to the CSSWG."  Part of the challenge is that it is NOT, in
   fact, a strict subset; it's a somewhat different set - I'm sure there would
   be heavy overlap, of course, but the goal was to a) open up the
   contribution process and make it easier, and b) be sure to delineate
   carefully things that are on the water slide to becoming RECs, and things
   that aren't (yet).  For a given issue, even a given CSS issue, I don't
   think it's true that incubation needs to block on, say, you or DBaron's
   attention.  Sure, for many features there's a point where it has to fit
   very well in the context of the rest of CSS, but that doesn't block
   incubation imo.

In short, two points:

   - Incubation doesn't have to mean the WICG.  I feel like I've said this
   in every conversation about WICG since it was created, but maybe I missed
   one or two.  If you want to take this spirit into the CSS WG and do
   everything under that umbrella, then I'd ask you consider what we're really
   trying to solve for with incubation (graceful failure, clear stability
   indicators, open participation with clear IP commitments), and figure out
   how to achieve the same aims in whatever forum you want.
   - Incubation doesn't shortcut review. The point was to have clearer,
   more complete proposals and explorations before putting features on rails
   to shipping as a REC, that's all.
