Yes, I could do that in 2 different terminals but that mode of working
is extremely useful, works when I don't have a windowing system, I'm
on the console.
Not having that model is a deal breaker for me, and I suspect a non
trivial number of other people.

You don't. But perhaps that model isn't super great.
There was no job control on plan9 and I can't say I ever missed it. If
I needed another terminal, I just swept open another window. Job
control, even remote access a la SSH (or telnet, or rlogin), are a bit
of an historical accident. If, instead, my computing environment is
the set of shared resources I've imported into my system, then I don't
necessarily need something like that. The plan9 `cpu` command, for
access to a remote CPU server, conceptually brought the CPU server to
you, not the other way around.
It was a very different model. And then we have pttys, speaking of pitys.
I'm not seeing how you do stuff like ssh into a remote system and have
job control, etc, work without some sort of tty.
