Looking at git.debian.org I found plenty of users. I did an archive
import of sid during Debconf and was only ran into 20 pristine-tar
failures (bugs yet to be filed).

The only thing I can think of (since we will keep support for not using
pristine-tar nevertheless) is using:

     Recommends: pristine-tar | dgit

gbp buildpackage has integration with pbuilder/cowbuilder (via
git-builder) and I know people are using it since its better integrated
into gbp since you don't need additional and it's documented in the
manual. The sbuild dependency is there to have people not pull in
cowbuilder/pbuilder so they can use --git-builder=sbuild.

Not sure what can be done here.

We're mostly using dch with "gbp dch" and I would also be happy to have
the dependency chain shortened.
