Yeah. Though RH have been apparently shipping breaking updates to
OpenSSL in RHEL 9+, so the conversation may look completely different
when we get to those EOLs.

True -- but I think that even if your split didn't land, surrounding
the necessary code with `#ifdef LIBRESSL_VERSION_NUMBER` would be a
big maintainability upgrade compared to "all code paths must support
both OpenSSL 1.1.1 _and_ LibreSSL which is
kind-of-not-really-the-same".
