When considering various options one has to be aware of multiple
global installations of Emacs.

Console is not always terminal emulator under X, or tmux or screen.

Not all computers have those installed. Not evey user can install
those. Majority of students and including professors cannot install
anything on the system. Those installation jobs may be done by system
operators or BOFHs. Emacs may run on multi user systems where users
cannot or need not have any permissions to install additional software
such as screen or tmux.

Then when looking onto the job control in my opinion every program
that runs in shell should provide facilities for job control from
shell. Today there are millions if not billions of installations of
GNU/Linux on various VPSes and dedicated online servers. Personally I
use 4-5 of them and during one month I may change few of them. So many
shell commands and work is done strictly in terminals.

When I am suspending job in shell I may just want to do the other job
while having one running. I may want to use shell and I may want to do
administration with some other software than one suspended.

Suspending jobs in shell is fundamental, single software pieces like
Emacs should not break those year long features.
