It can be real tough at the younger age levels with some of the smaller girls, when the umpire even if they crouch a little, is still looking down at the pitch above the girls head.
I don't actually find they miss low strikes, if anything at this level of like..30% strikes by pitchers, they seem to call almost anything over the plate that doesn't actually hit the plate. I wouldn't call it catcher framing given how few catchers actually catch the ball, but maybe pitcher framing? "That actually looked like a _pitch_ so it was probably good."
For some games, I want them called that way, too! Yes, the strike zone is important, but it's also important that I do not die from boredom.
