This is clearly not acceptable. You can't ignore problems like this one.
I saw you already broke debian-installer once with the former packages
that overflowed the 16K limit of cdebootstrap. Now it's the turn of
reprepro and this one is harder to fix because there are real servers
running stable version of reprepro, etc.

The algorithm is one thing... but the design of your tool is another
thing.

dpkg has dpkg-shlibdeps to build dependencies based on exported
information by various package (through
/var/lib/dpkg/info/*.{shlibs,symbols}).

cargo should build the same infrastructure, i.e. have a
/var/lib/dpkg/info/foo.cargo used by dh-cargo to build the correct
dependency.

Don't abuse the "Provides" field when you have such a volume of
interfaces to document.
