That's a self-signature, too (just not a key-uid binding one). But I agree
that signatures on keys are less popular with implementations than they
should be. OTOH, this is not directly related to the key packet format.

It is possible, but in many different ways. Implementations are generally
not interoperable. This stuff must be standardized, IMHO.
