So we'd have to gauge its usefulness overall, and see if it makes sense. Are 
there any apps which really use it, i.e. also provide whatsthis hints 
consistently?

Otherwise, perhaps we should review those apps that request the "?", and in 
case it's nonsensical (such as in systemsettings), remove it.

Do you know how to find this "provides context help" API?
