What that phrase is trying to say is that nobody will force any of those
older ports out of the archive -- at least that's what the release team
and DSA members present at the meeting told me. It's expected that, at
some point in the future, it will be technically or practically
impossible for porters to continue to support those ports; that's when
they'll be dropped.

There are already procedures in place in Debian to overrule a delegate's
decision, if necessary. It's pointless to duplicate that.

This is not specified, and deliberately so. Any way you can come up with
that demonstrates 50 users should do (although it may require _active_
users; the idea is to avoid ports that are only being used by the build
daemons)

It shouldn't, and this was confirmed at the meeting. That's where the
confusion lies.

Ditto.

Yes, and this happens. I've already had requests to modify my
Architecture: line in my nbd packages for new ports, such as amd64 and
ppc64, even before they're part of the archive.

It's not hard to do this, and if there's a valid patch, people usually
apply it.

Yes.

Oh? I didn't know. Please send me details in private mail.
