If we do that, what happens to other objects that were added to the
containing schema, sometime after creation of the extension? Surely those
should not become dependent on the extension.

I disagree that this is a bug at all, much less that we should back-patch
a behavioral change here.

As a refresher, the docs also say this about the target schema for an
extension, about two paras down from where you quoted:
"The target schema is determined by the schema parameter in the control
file if that is given, otherwise by the SCHEMA option of CREATE EXTENSION
if that is given, otherwise the current default object creation schema
(the first one in the caller's search_path). When the control file schema
parameter is used, the target schema will be created if it doesn't already
exist, but in the other two cases it must already exist."
I do not recall the full reasoning for this inconsistency in behavior,
and since I'm on vacation I don't plan to go looking in the archives to
find it. But this behavior was most certainly explicitly discussed and
agreed to when we put in CREATE EXTENSION. If you want to lobby to change
it, you'd better look up that discussion and refute the arguments therein.
Simply asserting your opinion that a four-year-old behavior is wrong is
not going to get you anywhere.
