Same - this feels equivalent of some rando making a repo called "Windows 12" or "Linux 7".

LDAP2 or nextVFS... but point awarded. Feels that way because it is. Though my examples aren't great. These things just are; not really versioned. I don't know if major differences would call for ++

A better 'working name' would be something like sshttp3, lol. Obviously not the successor to SSH2

You mean like cryptocurrency bros naming something "web 3.0"?

C.f. “JSON5”.

I think you meant to say, “YAML3”

Eh. JSON forfeited version numbers, and if this analogy ran all the way through then we'd be looking at a scenario where SSH is based on HTTP 1 or 2. In that situation calling the HTTP/3 version SSH3 would make a lot of sense.
