no, it's because it's simply a pain. once you start dealing with keys, 
you have to start dealing with keyboard layouts, at which point you have 
to deal with modifiers. it's quite trivial to make the driver spit out 
keycodes (after all, any keyboard does it), but people would rather 
configure it as "ctrl shift a", or whatever. and that again depends on 
the layout. I'm not saying it's impossible, it's merely annoying, a 
source of bugs and a questionable use case to begin with.

Because in the end, what you're trying to do is to cope for missing UI 
features by adding a hack to the driver. Hardly any configuration I have 
seen so far wants the button do send "ctrl +". They want the button to 
zoom, but that's only possible by making it send "ctrl+". The right fix 
to the issue is to fix the applications so that button actions are
