This ... seems to be confused.  We already *have* NSS and GnuTLS in a
pluggable way.  In addition, the first bug report you cite in [2] was
incorrect and needlessly inflammatory; the author read a tweet that
was factually incorrect and flew off the handle.

I won't suggest that our SSL support cannot be improved, as I'm sure
it can, but I think your gross strategy may have to be reconsidered.

This seems like something that shouldn't be folded into individual
applications, but provided as part of the system.
