I don't think there's a policy.  But many packages add to
auto-mode-alist which is quite similar, no?  It also changes the
behavior.

I think adding the handler is appropriate here at least if you've
installed debbugs explicitly.  I have to confess, if debbugs was
installed as a dependency, then having it add a handler could
potentially be annoying.  Though I think no other package depends on it
so far.

Maybe we could add a boolean defcustom to debbugs which tells if the
handler gets added?  But would that work?  I guess no because nowadays
package activation happens before loading ~/.emacs IIRC...

So basically, in this very specific case, I'd say let's make a new
debbugs ELPA release and see how many users start screaming.

And maybe we might even get positive reactions.  I activated
bug-reference-mode in Gnus summary and article buffers, and it is
totally awesome to follow bug#11991 references immediately with
debbugs. (One thing missing here [only in my ~/.emacs] is that you have
to set bug-reference-url-format to the GNU debbugs URL yourself.)
