( Using same time "tls-ports" and "tls-commit" member )

Intresting idea.

So "tls-ports" lists safe ports and that imply that other ports
are not safe to use for that origin.

Was that what you mean ?

I'm not sure that this works.


Per RFC7838 client does not need even read
It is enough that there is valid certificate.

I guess that load balancer can just filter
Alt-Svc: -header fields from response instead.


If there is no service wanted, then that port
does not include same /.well-known/http-opportunistic
(I guess).

However "tls-commit" does not require that that
alternative port gives same /.well-known/http-opportunistic
representation as the origin did for the http-opportunistic 

On that case it does make sense to require 
that /.well-known/http-opportunistic are same
on both on alternative and origin.

( I suggested that on

| 3. Server Authentication requires that

| Now that is not required for commit.



Currently "tls-ports" does not have specified that way.
It does not have negating power.
