I never understood those kinds of changes. If you really, really, really want to rename something, deprecate the old thing and make it an alias for the new thing. Don't delete it. Just add compatibility shims. Then after 5 or 10 years, take a pulse of the community. If they've mostly migrated off, go ahead and delete. If it's still actively used... Keep it, or even undeprecate it because clearly it's wanted.
