And for example, if RH does not backport openSSL 1.1.1, you will not get 
EDDSA certificate support for TLS? 1.3.? Now you might not care about 
this for your servers and just continue to use ECDSA certs. Clients will 
increasingly encounter EDDSA certs and it will be interesting to see how 
this is handled in older clients.? We have had years to spread support 
for ECDSA before it started appearing from servers.? May not for EDDSA.

Self-touting, I have an Internet Draft out on using openSSL command line 
to build an EDDSA pki.? I did the work on Fedora29-beta.

I think all the other TLS 1.3 features are in the latest 1.0.n version 
of openSSL.? Of course that is ALSO a backport issue.

I have been told that if you set up your client to only accept TLS 1.3 
connections, the Secure Internet gets really small really fast...

I am under the impression that TLSv1.3 support appeared in 1.1.1 so I 
don't believe that you could do any TLS 1.3 with prior versions.

Yeah, I was kind of hedging my comment that maybe something for 1.3 
would be in the earlier version, but yes, all the TLS 1.3 work was 
focused on openSSL 1.1.1.? I was personally focused on EDDSA support.

So a number of items have to appear in C6 for it to support TLS 1.3.? 
More slowness in TLS 1.3 availability.? Kind of flies in the face of a 
claim made against my HIP protocol which 'requires kernel level changes'
and thus too hard to deploy.? TLS is an upper layer protocol and changes 
easily roll out.

Yeah, right.
