Given we've already had this conversation (about the inappropriateness
of binary blobs in what should be FOSS software) once, I feel the need
to say that the more times this happens the less trust people will have
in GnuPG and the GnuPG ecosystem.

It's *really* *important* that the major tools surrounding GnuPG be
FOSS, and can be built entirely without depending on closed-source blobs.
