I thought about that and decided it wasn't worth checking for. If an
extension author puts in an extension not in requires it's on them as the
docs say it should be in requires.
It will just pretend that extension is not listed in no_relocate.

Yes this is intentional. As Tom mentioned, if for example an extension
author decides
To schema qualify @extschema:foo@ in their table definition, and they marked
as requiring foo
since such a reference
is captured by a schema move, there is no need for them to prevent relocate
of the foo extension (assuming foo was relocatable to begin with)
