Not 100% sure if following would have a positive effect on the
ports system, but it certainly would be useful for FreeBSD+pip
users if someone has the bandwidth to get involved upstream (the
Python cryptography project: https://github.com/pyca/cryptography)
and help them publish wheels for FreeBSD.
That would mean, e.g. that pulling rust is not necessary for pip
install cryptography.
