Right.  That has never been allowed, and I don't see the point in
permitting that.  libgnutls and libgnutls-extra are tightly coupled.

Yes, I think that would be nice.  All the code could then do something

 if (_gnutls_cert_vtable[certtype])
   _gnutls_cert_vtable[certtype].process_server_certificate ()

Would you like to propose a patch for that?  I'd expect it to only
require changes to gnutls_cert.c/auth_cert.c...
