We have had backlash from these types of changes in the past where people
plan on making a change like this without the announcement happening early
on and being communicative early about this being something that will
likely happen in the future would be a good thing as I see it. It allows
the people that put their time and effort into something that will likely
be deprecated to make a choice using the available information (sketchy as
it is) as to whether they want to start such an effort for a new theme or
want to continue the effort of maintaining an existing theme.

I also agree with Gavin that there are more important things to do than
update the theme docs. Being communicative about this will also give theme
developers the opportunity to make that same decision regarding their time
just as we are doing in relation to the theme docs and our time.
