This would basically cause the same problems as with the current path:
dependency.

It is still required to rev-upgrade all ports after switching the
variant. All binary archives built with the default option would not
work on a system with a different variant choice on mp-ssl-lib.

Explicit variants in all ports are the only way to prevent that, as the
port contents will actually be different depending on whether you link
against openssl or libressl.
