There are plenty of associations who do this: https://worldhickoryopen.com/ I still play with my grandfather's persimmon clubs about 25% of the time. It's just a coordination problem... but once the dominant professional association the game changes forever, because the vast majority of people just want to emulate the pros, because they grew up dreaming of becoming pro.

So why do I feel the need to dislike golf? I'm a white skinned, middle aged male and my job title is Managing Director. Obviously I should be a passionate small white ball smacker. No I'm not.

There's some precedent already. Drivers have limitations and most manufacturers are under them (ie just at the limit for things like moment of inertia) but drivers that are outside regulations are available to buy online. Also horizontal distance metering is allowed in competition, but not vertical distance. Most rangefinders have a visible external switch to disable vertical distance. One could expand from those two places where we by regulation already use sub-optimal equipment.
