This reminds me of an earlier discussion we had that somehow petered out before it resuted in usable improvement, https://lore.kernel.org/git/xmqqtuo9kgo0.fsf@gitster.g/ I do not think it is feasible to immediately rename the two choices to SSL/TLS vs StartTLS without transition period, but the first patch in the three-patch series there to update the documentation alone may have helped this case. We may also want to error out when seeing an unknown option other than 'ssl' and 'tls', as the necessary first step to make it possible to later safely accept StartTLS as a synonym for 'tls' and 'ssl/tls' as a synonym for 'ssl'.
