Thanks, that makes a lot of sense to me.

I retract my second in message #13, but I'd be happy to review a patch
that provides a more targeted carve-out to support existing practice
without making the problem worse.

I also would be happy to see a separate thread to discuss expanding
supported packages that can be put in build-deps, for example as an
email thread in debian-boot@ or as a wishlist bug against dpkg with
debian-boot and apt@packages.debian.org cc-ed.  If I understand
correctly, it's a little different from build-time deps because there
is not a standard way to install a udeb or deb on the build system.

Thanks and hope that helps,
Jonathan
