Yeah, that was exactly my thought when I read Russ' mail. dpkg currently
does not key on that, but just because there was no easy way to fetch
that field from where it needs to be accessed:

  <https://anonscm.debian.org/cgit/dpkg/dpkg.git/tree/scripts/dpkg-genchanges.pl#n401>

but that will be fixed with something like this branch:

  <https://git.hadrons.org/cgit/debian/dpkg/dpkg.git/commit/?h=pu/automatic-dbgsyms>

Yeah, and that reminds me that I should document that in deb-control(5)!
