That would be very useful as it would reduce the boilerplate but also
solve some of the problems of hijacking the clean target, notably the
fact it is executed twice by some tools (like pbuilder, once outside,
once inside). I didn't propose anything like that as I was thinking it
was very likely to be rejected as it is of no use for proper Debian
packages. While my Perl is a bit rusty, I can propose some "dh_fetch"
helper for this if there is no huge opposition against this approach.

Yes, it would help too.
