Yes, but that would be the _Debian_ cryptsetup package which
is derived by the Debian cryptsetup package maintainer from 
the proper cryptsetup package...

That is actually a good idea, but they are created by
the Debian project cryptsetup maintainer, not here.

On the Debian project website, search for the cryptsetup package 
in the package search. The  Debian maintainer and development team 
addresses for cryptsetup should be there. Just contact them.

I don't think so.
