 Yes, but the real question then is: why would mbedTLS ever be more suitable for
your needs than openssl (when used as a backend for libssh)?

 I remember there was a patch doing something similar for another package at
some point, and there the explanation was that (IIRC) with gnutls you could use
a crypto token but with openssl you couldn't. So, if there is something like
that at play here as well, please explain it in the commit message.
