Hmm, do you have a definitive reference for that?  All I can find from a
quick google on seemingly relevant terms is a year-old e-mail exchange
between Goswin and aba about a specification of the file format, which is
fairly disjoint and doesn't really explain the issue properly.

Why do you need debian/changelog if you're using debian/control?  Surely
there could be an alternate means of specifying the package version number,
since you're not restricted to using the Usual Debian Tools -- remember,
absolute minimalism here...

It's actually quite a fun mental game, this: "What do I *really* need,
rather than what I'm accustomed to needing".
