You asked me why I thought it likely that vendors would pick up -one- additional method in the specs. I answered; relative to more expensive standards such as SVG, which have taken a lot more time to implement.

SVG is already supported by every major browser implementor.

That said, implementations are lower priority than authors or users
when weighing features.  In general, users are most important, authors
are below users, and implementations are below authors.  (Below
implementations are spec authors and theoretical purity.)

The focus ring API was specifically designed to offer some benefits to
the author, and to make it reasonably obvious when they're doing it
right.  This fulfills several of the criteria I offered up previously
concerning what a good accessibility solution would look like.  (Note
that it didn't *have* to do so; in fact, omitting those qualities
would have made a simpler and more understandable API.  But that
simpler API wouldn't be used as much, and thus accessibility would be
helped less.)

So far, the same is not true of binding paths to elements and somehow
figuring out z-order.

(Just creating paths is high-value for several reasons unconnected to
accessibility, but the simplest solution to those problems does not
help accessibility.)

Sigh.  I'm trying to make sure you're actually solving real problems.
That's all I've been doing this entire time.  This is a fundamentally
realistic stance that's proven effective in the past.
