Isn't a balance of usefulness vs fragmentation vs trusting developers?

When touch events are exposed, I'd expect that developers who care about
having a board appeal will have alternatives for users without a touch
interface but having a web page be able to respond to touch events seems
useful for web pages to do to shine in that context.  (In fact developers
are inclined to provide this other interface to have the broad appeal.)

Doesn't the same thing apply to these other cases?
