[selectors4] Features to Defer

Prompted by plh, Tab and I just went over the Selectors 4 spec,
to figure out what's ready to polish up and send to CR and what
looks like it should stay in WD. Here's a list of what we propose
to keep and defer:

Keep:
   * Everything in Level 3, obviously
   * case-insensitive attribute selectors
   * :matches(), :not()
   * :dir(), :lang()
   * :any-link, :current, :past, :future
   * CSS UI selectors, possibly other than :read-only / :read-write (see below)
   * :user-error

Defer to L5 or Need More Info to Decide

   ? :has()
       Propose to defer.
   ? :focus-within
       Will keep if there's impl interest

   ? :drop and :drop()
       No idea, need info on impl status / interop
   ? :read-only and :read-write
       Vaguely recall someone wanting to drop this...
   ? :placeholder-shown
       Need to check impl status

   ? :blank
       Need to check impl status, would prefer a new name
       (that doesn't evoke empty input fields)
   ? :nth-child( An+B of <selector> )
       Want to double-check satisfaction with syntax, impl interest
   ? >> descendant selector
       Bias towards dropping, want to check with implementers

   ? Column combinator
       Want to double-check satisfaction with syntax, impl interest
   ? :nth-column() pseudo-class
       Biased to at-risk

Please send your thoughts on this list. :)
