The problem is that it's quite tricky to know when the switch happens.

And the amount of people who dare to touch the tty code is very small.

So it's simpler to just disable the feature, when people who do need
the TIOCSTI functionality are actually either running as root (or can
easily acquire the necessary privileges), or running X and can thus feed
the terminal though an X API, or can as well just run an intermediary
"screen" instance.
