And if "serious" skaters care so much about this - why didn't I EVER HEAR such conversation until the last 4 years. Did Oksana UR? Did Kristi flutz? Did Boitano and Orser lip? Did Midori UR her 3A? Did Katerina ever UR? What about Linda, Roz, Dorothy, Janet and Peggy. I saw many of those skaters Live and also on TV. I never heard all this talk that only "true skating fans" care about...
Commentators back in the day did point out "cheated landings" (underrotations) and occasionally wrong edge take-offs (the word "flutz" is much older than the CoP.)
But as you say, they were much more likely to harp on errors on the landing -- double-footed landings, stepping out, hand down, even just taking a wide turn with a swinging free leg.
How the judges factored in all these things, nobody really knows (at least I don't.

) But the skaters
were able to receive feedback from the judges about why they were marked down and what aspects of their skating they needed to work on.
I think one of the goals of the new judging system is that the ISU wanted to run a tighter ship. You should not get credit for a triple jump if you don't rotate three times, no matter how pretty you look doing it, and no matter how much the audience ooh's and ahh's.
You should not get credit for doing a sit spin if, to quote the latest clarification of the rules, "the bottom of the buttocks is not lower than the knee."
Should you get credit for a Lutz jump if you do not take off from the back outside edge?
Edited to add:
No, no, a thousand times no!

Actually, this (Kristi's Olympic LP) is a good argument for slo-motion instant replay. In real time, it looks like she did flutz (she was not all the way on the back outside edge for most of her approach) But in stop frame, she has a perfect BOE at the moment of toe-off.
Midori Ito, in contrast, had one of the best Lutzes ever. But some people thought the leg wrap was unesthetic.
