Maybe we can teach Britney to not migrate the packages to release pocket if
they are uninstallable within their component?

This way almost nothing will change — just like now such packages will be stuck
in proposed (the only difference is that they will build there).

But on the other hand we'll have less MIRs for the build-dep-only stuff, which
is quite common (i.e. the JS minifiers or documentation generators).

I think most of the packages stuck in proposed are auto-synced from Debian
(I really hope that Ubuntu developers who upload their packages specifically
to Ubuntu do care about the migration of them). In this case there is almost
nothing we can do to improve that situation anyway… (maybe advertising the
excuses page a bit more so that more people look at it?)

In any case, I'm all for Dimitri's proposed change as it will allow us to get
rid of lots of Debian delta and also stop doing strange tricks like one we did
for jQuery to make it build.
