Which is why there is HTTPS and SVCB. If you look at your recursive
server logs you are likely to see queries for HTTPS being made as
browsers are starting to make queries for HTTPS (a.k.a. TYPE65).

The only thing difficult to map was non-default ports and that could
easily have been addressed. Remember SRV required a seperate RFC to
specify how to map existing services on to it. HTTPS just prefixed the
label "_<port>”. That could have easily been done with SRV.
HTTPS and SVBC are just SRV on steroids.

But how much has been implemented in CGNs and how many ISP’s
enable it if it is implemented? Getting IPv4 continue to work
just add layer upon layer of hacks which we are all continuing
to pay for.
While we debate more and more services are enabling IPv6 and
the traffic is shifting to IPv6.
