 > It's worth having a discussion about how long we should maintain core
 CSS

 Yes, completely agree. The WordPress "philosophy" on backwards
 compatibility has always been to maintain it as much as possible. This of
 course applies to CSS changes: if "breaking" back-compat can be avoided,
 it should. There are some efforts to better organize and review wp-admin
 CSS, hopefully this will be discussed there.

 > If we do remove core CSS that's used by thousands of plugins, it would
 need a dev note - preferably published sooner than RC1.

 Right, exactly. Removal of deprecated code should at least happen in a
 separate ticket, with proper testing and communication.

 > Let's just restore those styles, and we can have a discussion about
 long-term maintenance of CSS separately.

 Sounds good :)
