Yep. Both of those issues are purely in the realm of theory. There are
things that are possible with OpenPGP that are not permitted by certain
(or all) implementations of OpenPGP. But there is nothing stopping you
from writing your own hack that adds UIDs to other peoples keys (except
that you would piss a lot of people off), or writing a patch to a
keyserver so that the owner-update-only flag is treated properly.
