Is it possible to mark specific entries to be ignored?

[Keavon]

I'd like to have a set of enum variants live at the top, with the subsequent ones alphabetized. It is possible to tag those variants to be ignored (so they can go anywhere)?

Ideally something like #[remain::ignore] or #[remain:here] would be nice to place above items that I want to stay put. That's especially important for match blocks that need to match a default case at the end.

This apparently already exists as #[remain::unsorted] but it's undocumented.
