The only one that still shows up for me is core/classic.
Wonder if we should remove any styles that are in theme.json I can do that and just add it to this PR if you want.

Actually, I don't think this is going to be an issue because we're going to include that one (for legacy content), along with the Cover and Gallery blocks as well.
