I don't think you could forbid it; this is a feature that people use,
and it would be a restriction that they wouldn't understand. "Why can't
I upload this file from my personal documents directory on the company
file server?"

Another option would be to say that for file upload controls, this
value/event is a) asynchronous and b) optional for user agents.
(Optional also meaning they could fire it for some paths and not
others.) In this case, behaviour would revert to the WF 1.0 behaviour.
