I assumed that.  I'm more concerned right now with the Policy compliance
of the contents.  Ubuntu talks about using a separate package extension
because they don't need to be full packages, but there doesn't seem to be
any particular motivating reason for that -- in other words, I still don't
see any reason why they can't be regular Debian packages.

Excellent, thank you.  That's certainly my intention.

There are multiple places in the archive where two binary packages install
binaries with the same name but different contents, where for some reason
alternatives cannot be used.  If using the binary-id method, this doesn't
matter, but if using the gnu_debuglink method, those debug packages also
have to conflict.  Having the debug package depend on the corresponding
binary package takes care of this.  (So does, of course, using binary-id
