I certainly agree that this is a problem, but I don't think anyone is
suggesting that.
I had always assumed that if you were in a cert-based system like TLS, the
clients would generate self-signed certs purely for use as a key transport
mechanism (see DTLS-SRTP as an example of a system that does this.)
