I was actually going to start a new thread about it.

On the one hand, nothing in the opMove DIP is directly affected by this. 
On the other, if we're moving away from "copy and then fix" mentality, 
then opMove should also reflect this.

The problem is that the alternative solution has a much bigger impact on 
backward compatibility. I'm really tempted to try and push this DIP as 
is, only renaming "opMove" to "opPostMove". This way, we can push the 
simpler version as is, and when (and it will take a while) "this(this)" 
deprecation finally comes, we can implement "opMove" as an in-process 
user hook.
