I think it's spectacularly naive to assume LibreSSL will be widely adopted beyond FreeBSD just because it's a cleaner codebase.
Think OpenSSH -> OpenSSH-portable.
What if it also had fewer bugs, is more receptive to contributed bug fixes, runs clean in Valgrind, etc.?
OpenBSD is already reaping the benefits from a better TSL implementation in -current so it's a win for our project as well.
This is a win win scenario.
