To clarify: you did mention two use cases: one being to improve
debcheckout, the other checking the Vcs-* fields (if I understood
correctly).  I had forgotten about them because it is not clear to me
they need the dirty bit.

The first use case (debcheckout) cannot benefit in any obvious way
from knowledge of dirty trees.

For the second (Vcs-* checker), I guess it could bail out for dirty
trees.  Unfortunately, 'dirty' trees are pretty common when including
files generated for the source package but ignored by the VCS, e.g.
from autotools), so this checker would not work for a large number of
packages.  Maybe a horrible hack would help: check that very few files
were modified, or that all the files changed are in .<vcs>ignore, or
something like that.  Such a hack would not really benefit from a
'dirty' bit.

So I am interested but not yet convinced.

Hope that is clearer,
