So... domain:authInfo is not good enough to authenticate the owner to do the transfer...
but contact:authInfo is good enough to retrieve contact data and then authenticate the owner
to do the transfer.

"Interesting". 2 authInfo but seemingly one has more "power" than the other.

"to only one registrar": no, to any registrar having this token. Exactly like
domain:authInfo allowing transfer to any registrar having it.

So then why should a registry force anything? We are back at the fact
that registrars wanting to support that scenario will indeed need to put
resources for it, and hence if there is an EPP extension to support that
they will implement it.
The question is how to do it in a smart way to not disrupt all other
registrars NOT wanting to support this scenario.
