If you do that a 2nd time to a pro, let's say Mima Ito even, then she's gonna be on it quicker than flies on shite and your gonna get a ball you can't touch. I'd even chop it with the edge of the racket just to make a point!
I think
@Attitude in post 31 has given very good reasons.
If it did work against very short players tho, I think that eventually morals or ethics of the game would come into it a bit.
When watching that video of the kids we can all see that it's a very crappy way to win, and the kid doing that serve isn't really helping himself in the long run. I don't think many pros would be happy to beat Mima Ito this way, exposing her height to repeatedly hit a serve that she cannot reach..... I could be way off here, maybe they're all just cut throat but I wouldn't be happy to beat someone that way.
Do you really not think it would be figured out at pro level very quickly?
What are the specific reasons that make you think it could realistically work?
