Well, bring 7344 people to the table, I don't care how biased
it is... [1]

Of course a terminal multiplexer (read tmux) it is not the
same as job control. It is better, that's why it has
superseded the C-z/fg practice.

To experience one immediate advantage - literally immediate -
compare opening a new tmux pane to doing C-z. With tmux, you
still have interactive control over Emacs, or whatever other
of a dozen or so applications and interfaces you might have
open, visible at the same time, with tmux panes all over
a huge monitor. Including, if you wish, a dedicated pane, just
to do job control! Compare this to suspending Emacs and then
'fg' it back and forth.

You also mention the 'persistent IRC' stunt that can be done
with tmux:

  tmux attach [-t X]
  tmux kill-session -t X
  tmux list-sessions
  tmux new -s X-s 'tmux set remain-on-exit on; X'

and, I'm sure, the tmux expert can think of many more.

There is even a book on tmux:

@book{tmux,
  author     = {Brian P Hogan},
  isbn       = {978-1-93435-696-8},
  publisher  = {Brian P Hogan},
  title      = {tmux: Productive Mouse-Free Development},
  year       = {2012}
}

Also, you seem to say this is such a fundamental practice,
however with zsh, it isn't even enabled by default. (IME
people seem to use bash, zsh, and - the OpenBSD people - ksh
(which is actually rksh, for legal reasons). FTR it _is_
enabled by default on bash and ksh.)

So it isn't even enabled by default on one of the most
commonly used shells.

tmux should be many magnitudes more powerful for several
reasons, in this aspect and others. Use it and get into the
game :)
