Not as such (though asking the os what the current keyboard layout is 
should be possible on any reasonable os via the platform analog of 
XkbGetKeyboard() ?)

- A user with a hebrew os keyboard layout who liked auto-switching could 
define that in an ltr context, an emacs input method revpar* should be 
switched to. That input method would yield "(" when the os sends ")" to 
emacs. A user with a us os keyboard layout who wanted to use the hebrew 
emacs input method and also auto-switch could use "hebrew" and 
"hebrew-revpar" rtl and ltr input methods.

Because it would always insert the appropriate character?
