Following that same reasoning, we shouldn't have jit-lock.
And post-command-hook.
jit-lock is tolerable because it is used in a very narrow way, for
updating text properties. If it were used more broadly, it would
be a disaster.
post-command-hook is also used in narrow ways, and it doesn't
cause anything strange to happen just because you move the mouse.
Timers need to be used in a clean way if they are not to
cause trouble. In any case, switching windows does not cause
timers to do anything.
If I understand what mouse-autoselect-window does, it only causes
switching windows -- it does not run Lisp code.
Yes, these things should be used with care, but that doesn't mean we
shouldn't provide them, because they can be very useful.
What is a very useful application for running code when the mouse
moves out of the Emacs frame?
