Looking more into it, it's really not easy. We cannot easily know
whether the layout will include level3(ralt_switch), and so if ralt will
be allocated to something.
The base problem is that we have a default configuration that leads to
a conflicting request: ralt+rshift to toggle group, and ralt to switch
level3.
I'm thinking that the default configuration should only enable
lalt+lshift for toggling group, so that ralt+rshift can either remain
the default Meta_R or level3 switch, depending on the layout, without
conflicting with group toggle. That way, only people explictly
requesting alt+shift (i.e. both lalt+lshift) will risk getting the
conflict if they don't realize that it conflicts with they level3
switch.
