+1 to TLS 1.3. My strong preference is TLS 1.3.
Reasons have been advanced ad-nauseam.
Just a couple of additional thoughts:
1.3 is in the protocol. So there.
"Perl 6". Just because you advance a version number to a big one,
doesn't mean that businesses will see the justification to upgrade.
I think it is interesting. A good place to take it up is the pkix
mailing list anyway. See what people say.
As far as experimenting, it is not difficult to create a new X.509/PKIX
extension. Just create an OID for your experimental use in whatever arc
you have at your disposal, and go.
