Not really: 99.99% of the time, ttys are controlled by a shell, or some
other program, so if we use M-x make-frame-on-tty RET we get into
a situation where 2 programs use this tty at the same time, without any
synchronization between them.  I've used it for debug purposes (to
circumvent the server.el and emacsclient code), but it tends to give you
various forms of display corruption, so it's not really appropriate for
a user command.

It's not crucial indeed.
