There would be a keysym that means "there is a 'W' printed on this key", 
and a keysym (or several) that means "this is a Shift key" and "this is 
a Ctrl key", and the client would wait for them all to be down.

Yes this would not work if there was no key with a 'W' printed on it on 
the keyboard. However in real software that is not how it works. 
Shortcuts are written as "Alt+Shift+4", not "Alt+$", they are based on 
physical keys, not on the symbols they can produce.

If software really wants to say "hold down Alt and type a 'W'" then it 
has to talk to the input method, since that is the only thing that knows 
how to make a 'W' (imagine an input method that produces 'w' when you 
type 'u' twice, perhaps in a compose sequence).
