I saw a Championship referee kick the ball towards player for a throw in last Friday!
Ball was very close to him & had stopped, and no players complained and I doubt only fellow referees in the crowd would have even noticed - don't really see a problem with that type of action.
Agree has an AR you shouldn't stop the ball or anything that can be seen as "helping" the team about to take throw/free kick but in certain circumstances, like I saw on Friday, its really not a big deal is it?
