What does "get out of hand" mean? What unwanted consequence would you be preventing with this check? The point of imposing a limit is so that buggy code with infinite recursion will (hopefully) stop compiling before the system runs out of memory. So it's a check to make accidental infinite recursion fail sooner, rather than grind to a halt later. I'm not aware of a good use case for "I want some templates, but not too much".
