Goalies, and back through the goal

Okay - so is this anew rule being proposed, or has it always been like this? I would never have counted these in the past, but then again, I never really thought about it.

Can we simplify this and just say out of the D?

Out of the D is probably the simplest, but I still reckon that if it comes off a defender's mallet, whereever it is, it's a goal.
