I found some explanation of the original reasoning in these threads:

It seems like it's for pg_dump, so it can avoid outputting the extension
templates and just say "VERSION 'x.y'" without worrying about which
version it needs to start from.

That seems like a legitimate purpose, but I think we can come up with
something that's a little easier on users and easier to document (and
name). Perhaps just find the shortest upgrade path to the version
requested (using some arbitrary but deterministic tiebreaker)?
