Ah, but the result is much simpler.

Some other real world data (Google QUIC experiments) already tell us
that a sizable part of the Internet (was it 7 %?) is not reachable via
UDP at all.  This just ups that number slightly for IPv6 and UDP
protocols that don't have their own segmentation.

UDP, it was nice to have known you.

Maybe what we needed all along was a better TCP that allowed data to
be sent on the first packet.

FWIW, TCP does allow you to send data in the SYN.

However, it's not
friendly with DoS mitigatons such as SYN-cookies.

Thanks!
