I tend to think the same -- but sooner or later it will happen ;-)

With three archs currently I tend to agree. But let make this four or

- request build
- build fails on x86_64
- fix + request build
- build fails on ppc
- fix + request build
- build fails on IA64
- fix + request build
- build fails on sparc
- fix + request build
- done

- request build
- build fails on x86_64, PPC, IA64,sparc
- fix + request build
- done

A lot easier IMHO

Yes, maybe there should be such a maintainer-group also when such big
changes are ahead. But those changes happen only about once a year (or
even rarer) with together with bigger Core updates.

Arch-Problems can happen each day. And then the maintainer needs to know
whom to ask.

At least two imho.

In some packages, not in all. But I don't have a strong opinion here.
Imho we simply should use extras/testing (or something like that) for
this. Put it there after building (before signing? Signed with an
automatic key?). If someone verifies push it after out after at least 2
days. If not, put it out after 14 days without verifying.

We agree here.
