It's not a huge amount of code to support that. I would basically handle it the same way I handle smart buttons - if you long press and drag, it would move the link point. The only thing is this could cause users to accidentally drag their link points instead of triggering it if they press too long. I'll have to see if this becomes a problem, and if so, then I would have to make this configurable. I'd have to add a lock/unlock option in the link window.

I don't see why it would be a problem here if it's not with the smart buttons, sure if you press too long and drag instead of just tapping the link might move, so don't.   haha.
My point is that treating links the same way as smart buttons seems easy enough at least initially.  I wouldn't account for a potential problem if it might never be there. 
Keep it simple.
