Yes, that's true.  And essentially that's the case right now, too,
except that "clicking" it (C-c RET) is no no-op whereas it would open a
wrong (emacs) bug then.

Nah, what does that have to do with debbugs really?  The task is to set
the right `bug-reference-url-format' automatically.  How the bug report
is opened later on is handled by `browse-url-handlers' and
`browse-url-default-handlers'.

How about adding a defcustom `bug-reference-guess-url-format-functions'
and a defvar `bug-reference-guess-url-format-default-functions' being
lists of zero-arg functions guessing the right
`bug-reference-url-format' from things like VCS URL of the current file,
Gnus group, rmail, etc.  Again the "default" one would be for making
Emacs (packages like Gnus) hook in, the other is for the user.

I'd be willing to work on that.
