Several years ago, I added the openssl_options config knob to Exim,

This is a rough proposal, with not a single line of code written to
support it, but I'm looking for considered informed feedback as to
whether it makes sense to postmasters out there.

As I understand this, these sections have to be in a particular order,
so we need to declare where and in what order begin openssl, begin gnutls
(begin libressl ?) will go.
We could declare that only one is valid but, for people experimenting with
switching tls library, would it make sense to allow more than one since we
have declared that the openssl section will be ignored if the binary is
built with GnuTLS ?
