No, it means "fetch this with HTTP", it doesn't say "HTTP/1" anywhere
and if the user-agent determines that it can be fetched better with
HTTP/2 on port 100, then that's just fine.

Now, if a port number is specified, things get more hairy, and that
could be documented as a way to insist on a particular HTTP version
if my proposal is adopted.

Never attribute to malice what can adequately be explained by incompetence.
