Well, I always run the git version on my machine. But maintaining dpkg-dev
is enough of a job that I don't maintain many other packages... so I
don't build many other packages except for QA work or similar (like
investigation build failures with the new source format).

Well, multiple hours compilation don't buy us much testing of dpkg-dev.
That said the bigger packages are also those that make usage of the
advanced features...

Are you interested in writing it? :-) I don't see anything that needs to
be specific for each tool. Starting with a new sbuild option to
auto-install a new .deb in the chroot (and restore the official one
provided by apt) would be half the job.
Deciding what difference is tolerated is the second (more annoying) half
of the job.
