Such as?  Is the effect really any different?

It's very difficult and, worse, it might turn out to be unenforceable.
You'd have to count on signing keys being copyrightable, and they are
unlikely to be, and on signatures being derived works of both, which
is a tough call.  The whole idea resonates very well with the spirit
of the license, but we need more than that, we need it to be very
likely to work.  I suspect this is why the FSF has decided to take
another route to achieve the same (AFAICT) effect.

I'm not sure what you're asking.  GPLv3 covers additional permissions,
that are really no different from dual-licensing, so anyone can choose
to drop them when combining with works (including their own) that
don't offer such additional permissions.

Yes.  And the 'them' after the last comma refers to the users, not the
authors (although they can be users too), in case it's not clear ;-)
:-D

FWIW, I never felt offended by you, but I second your request and
extend it to all participants in the thread too, particularly to Ingo,
to whom I remember having directed some harsh words.
