	Indeed, I’ve misunderstood the code a bit.

	Not at all.

	It’s possible to subscribe to bug-gnu-emacs@.  It’s also
	possible to subscribe to nntp://news.gmane.org/gmane.emacs.bugs/
	instead; that way only the messages requested by the user agent
	(assuming one which does support both mail /and/ news) will
	actually be transferred.  No clutter to the mailbox, too.

	Moreover, unless I be mistaken, that’s the limitation of the
	debbugs.gnu.org instance – the software itself /does/ allow for
	such subscription.

	Yes.
