I agree that "the point is to push the limits in all the aspects equally".Jumps are more difficult and dangerous than spins and footworks. The point is not to focus on jumps only. The point is to push the limits in all the aspects equally. The point is judges do not do their jobs well because of bias and political games. For example if they do not automatically give above 80 for men who just need several quads yet poor skating skills, the issue would never happen.
If some jumpers believe they only need the number of quads to score huge, then why would they push their skating skills and other aspects? It is the judges' fault.
To limit the quads means to stop the progress of the sport.
