I'm not sure if that's what you were thinking of, but I know at least one
extension (that I'm maintaining) that explicitly relies on btree_gist
extension, as in "requires = [...], btree_gist" in the .control file.

Since you can't really tweak the control file on a per-major-version basis,
this will require some extra thoughts to make sure that people can release
extensions without having to tweak this file in some make rule or something
like that.
