I didn't mean to imply otherwise. But, as you say, this is equally applicable to IPv4 and IPv6. There were a lot of issues solved by IPv6, but "have even more room for non-TCP/UDP transports" wasn't one of them (and didn't need to be, tbqh).

I agree, although I am a bit surprised to see that we’ve used more than half of the protocol numbers already
