if i understand you correctly it would not help me if someone
would sign my key without my approval, so to speak.

What i meaned whith my initial post was that it should in the
future not be possible to sign someones pub key directly, to
prevent unwanted signatures. Sure one can revoke his/her pub
key, but how often would you like to do that if a "prankster"
has lot's of energy?

I also forgot to mention in my first post that it would also
require that Alice has to enter her secrets key passphrase to
authorize Bob's Signature Request Certificate, after validating 
Bob's request cert.

I think it would be a welcome addition for  a future version of
GnuPG.
