I think it would make it easier to interchange public keys.
I have tried over many years to encourage my friends to use pgp, one of
the obstacles was the extraction and interchange of the public keys.

I started to use smime recently and besides its flaws I have to admit
that the key interchange is easier (most likely be more insecure)

I think it does, but it sounds like a project for the (far) future.
