But isn't volatile.d.o supposed to *be* the out-of-band mechanism
(whatever out-of-band means here)?

Not according to my understanding of apt pinning. And in any case the
point is that I want to run a *stable* box. I am not keeping
consciously track with upstream changes to "background" software like
spam filters, so I didn't *know* that a 3.0 version was about to
happen. A user of stable should be *able* to remain ignorant about
such chages. That's what "stable" means.

See the long thread about spamassassin3. The highlight is that the new
version has a non-backwards-compatible API which makes certain other
software stop working.
I did not personally have any local scripts that depended on the old
API, but I might have had.

Then a decision has to be made respecting the users' interest in
having whatever local scripts they are using keep working.

"In the whole of Debian" is not the only concern here; I would say it
is not even relevant. Admins of un*x systems are *supposed* to write
a truckload of local scripts to adapt their system to their wishes.
That's the way it works. And our commitment in calling stable "stable"
is that those local scripts will keep working across security updates,
unless breaking them is necessary to close a hole. Similarly, if
volatile is to be any value added over pinning unstable or testing,
it must respect the same commitment.

If upgrading will break existing interfaces, then "when" means "after
the current testing freezes and is released as stable".

I'm saying that *new upstream versions* of mozilla with hundreds of
little interface changes, new preferences file formats, et cetera,
does not belong in volatile.

I do not understand that question either.

I'm not sure what consequences this example has for what should and
what should not be accepted in volatile. If the volunteer who would be
preparing a rule update would rather use his time correcting
spellings, we cannot force him. But that is probably not what you're
