[TLS] Re: Confirming PQ+T Signatures Consensus

[Richard Barnes <[e-mail]>]

Weak "no" on the basis of draft-barnes-tls-this-could-have-been-an-email
[1].

LAMPS is already doing the work of defining composite signature algorithms
[2].  Once that's done, just send email to IANA to register the relevant
code points.

I realize that PQ is the new hotness, but really, we don't need a million
documents touching every protocol.
