OK, that's what I thought. This seems like the root of your objection,
so let's focus here.

Is this because of the namespace issue, or is there another problem
here, too?

Agreed. Adding namespaces would best be done sooner rather than later.

An interesting idea to rely on schemas like that, but it seems a little
hackish. I'd prefer something that would be sane for a user to do
without the assistance of a tool. We can still recommend that they use
the PGXN format and the tool, of course.
