It's the other way around: The first implementation registered will be
used. Unless it fails to load the key, then the next registered
implementation will be considered. The latter could also happen if you
load a private key without specific type and don't have the pkcs1 plugin
loaded, only the openssl plugin can load such keys directly, the others
need the pkcs1 plugin to detect the type (or even to pre-parse the key).

That's due to the default plugin list (built by the configure script),
which is used to order the plugins if they have the same priority.
