I never knew about this so tried it out:-

The terminal goes full screen with no warnings and yes the little
maximise/restore window tool at the top vanishes.

Chrome does the same, everything except the current tab vanishes but it
puts up a warning about the F11 key for a few seconds.

The file explorer ignores F11 as does Evolution while I type this.
