DING! DING! DING! DING! We have a winner!

You do not wish your name or email address in a certificate's UID,
THEN DON'T PUT IT IN. Feed whatever text you wish through the hashing algorithm
of your choice and use that. Bang! You're done.

Just do it. OpenPGP and the software involved do not need any changes.
And as Rob pointed out, any changes would have a difficult time getting accepted.
