Indeed these are still what we use in production for i386/amd64. For
armhf and ppc64el we already use the new adt-virt-lxc and adt-run
directly, and that's what we want to move to next cycle, too. I'll
have a meeting with Antonio (http://ci.debian.net) tomorrow to discuss
the next-gen architecture, for sharing this between D and U.

Not really a bonus as such. The condition is that for a package X
upload, the tests of X and all tests of X's reverse dependencies have
to succeed, otherwise it doesn't propagate. If there are no tests, the
package still propagates once the other conditions are met (built and
installable on all arches).

It's better to have both kinds of tests, yes. They don't necessarily
need to be the same (and in most cases aren't). They have a different
scope and purpose.

That too :-) But I mostly value them for avoiding the introduction of
ABI changes or otherwise changed behaviour which break existing
packages. E. g. if we upload a new pygobject which breaks our
graphical installer (ubiquity), we'd hold pygobject instead of
noticing the breakage in the release two weeks afterwards, which is
how it should be.
