So you burden Debian with extra work without knowing whether this extra work
is needed or not.  You claim to throw broken packages at your users, but you
really don't know.  It is not just buildd time, it's man power involved with
such rebuilds, and getting it rebuilt on all architectures it did build before.

Please could you come up with a concrete example what exactly would be broken
in a haskell library package not itself using libffi?
