You obviously haven't had the fun of big corporate environments.

They might not even know who each other are, let alone trust each other.

And, there may be anti-social-engineering reasons that they are not allowed
to trust each other.

FWIW, I doubt very much that PGP keys are assigned by a security admin.

If you have to get public keys INTO the MUA,  you are (by definition) not
using DNS.

The entire point of these proposals are for publishing and
querying/discovery via DNS.

Or are you thinking private keys? For PGP and S/MIME, I believe those
are apples & oranges. Again, it is the MUA developer's responsibility to
make them
both work, and I expect a "pull" model vs a "push" model.
