Regarding wrestling from your knee(s), in my opinion freestyle handles it the proper way by immediately ordering the wrestler in question back to their feet. If the wrestler doesn't comply or repeatedly engages in that behavior they will quickly be issued a Caution and 1.
An addition to the six NCAA articles that currently define stalling from neutral could read as simple and similar to, "Stalling by Wrestling From One or Both Knees" Any wrestler who, in a non tie-up situation, goes down to one or both knees will be considered as avoiding wrestling action.
The "Robles" exception could be added to the definition to satisfy those who would insist upon the "letter of the law" application of the rule.
If the NCAA's focus is on awarding wrestling action then I think such a change is warranted. It would also be a simple rule for officials to enforce as there is no count involved, etc.
