It sounds like a way of enabling people to continue to avoid developing social skills. Wouldn't it be better to find a way to help people develop those skills instead?

Right, that's what I was talking about. This is a critically important social skill to be learned, not to be avoided. Learning how to deal with the fear of (and actual) rejection is a critical life skill, both in dating and otherwise. Avoiding it seems harmful to me.
