Ubuntu has gotten quite a bit of flack from the debhelper maintainer
for making independent changes in the past ([1], [2]), and doing so
again seems like a bad plan.

dh_install already has a --fail-missing option. It seems that this
would cover half of your use case, though I gather there are some
outstanding issues with it ([3]). CDBS also has a list-missing target,
though it doesn't seem that it can be made to fail the build, and also
doesn't cover your overlapping files issue.

It seems like it would be much more productive to work with Joey to
try and fix dh_install --fail-missing, and possibly add a new
--fail-on-overlap option or something. But in any case, I think that
adding a new debhelper script without consulting Joey at all will hurt
Ubuntu's image in Debian's eyes, and that's a bad thing.
