We've just made a similar move for hpnssh. We won't support anything
older than OSSL 1.1.1g. We've also dropped support for LibreSSL as a
whole until they implement EVP_CIPHER_meth_new(). We can't provide our
full feature set without it and I don't want to ship less functional
So I'm all in favor of this move.
