Well, right now there is nowhere to put the .ddebs either, and
they are really just .debs with a funny name too. Not very different.

How is a .ddeb package going to change things by the time it
gets into the archive? .ddebs will be there in the .changes file, and
the only way they are different is in the file name.

Why is it not trivial? I have such a hook in my pakages, and it
is not rocket science.
If you think that adding stuff like
objcopy --only-keep-debug lib_or_exec_file debug_file
objcopy ----add-gnu-debuglink debug_file lib_or_exec_file
strip --remove-section=.comment --remove-section=.note \
strip --remove-section=.comment --remove-section=.note exec_file
to a rules file is "not at all trivial", then heaven help us.
