While I like rules options and dials, they are worthless if they don't mix well with existing stat blocks and rules. If skills were re-designed to have different names, connected to different abilities, and have built in actions, that would require a full redesign of how all other rules interact with skills. If the actions are built in to skill training, it means that there is now a bit more exception-based design where there is only one way to do a precise thing.
That is full-edition worthy redesign. I would hazard a guess that is beyond the 2024 design intent. Sounds like extensive house rules/3rd party clone variation, rather than a viable option for Wizards to design
