True ... but have you ever used an interactive shell where
stdin/stdout/stderr are redirected to different sources/destinations?
... and restoring terminal settings on none tty's doesn't harm in any way.

It would be better to restore terminal settings on stdin just before
closing, if this is possible ... but if not, it could be a possible
solution to consider using stdout/stderr for this.

Programming in environments used/controlled by others is probably
(always?) like swimming in shark-infested waters ... and modifying big
programs of others is like calling that big white shark ... have I nice
time! :-)
