Yes. But then moving to double connection ID of variable length is also
going to require serious development and testing effort. To evaluate
that, I changed the "connection_id" type in Picoquic from uint64_t to an
opaque type. This was not simple, since the connection ID is used pretty
much every where, not just in protocol code but also in logging code,
test code, and of course test vectors. And doing that caused a couple
regression bugs, which I only found weeks later. Of course I am sure
that other developers can do it better, but still, they will need time
to work it out.  If we want to be done in November, we may want to test
that kind of stuff sooner rather than later.

Cool. Do you think we could have that spec merged before the London
meeting? Or should we start preparing for interop days in April and May?
