What makes you think the release binding wouldn't trigger just because
you pressed another key in the meantime? Yes, sure, you could write a
lot of special case code that figures out that Super_L is the key that
caused that other key event we just handled to have the Mod4 state bit
set, and remember it, such that it doesn't trigger. That's a lot of
special case code for an extremely fringey case though.
