Not buying any of this. Allowance of playing with "cue ball fouls only" rule is as deeply embedded in the annals of amateur pool as disallowance of nearly all the "do nots" that you cite. Allowing any of the disallowed things you cite wouldn't make the game more fun, more entertaining, or more rewarding for the amateur.
Any knowledgeable player who has played in leagues before knows that many (if not most) players (and many refs at the national tournaments) are clueless concerning how to accurately detect double hits and wrong-ball-first fouls. And bad or disagreeable calls in these situations, which come up often, certainly result in arguments, bad feelings, and less fun.
Would having fewer fouls in US amateur league play make the game more enjoyable for the bulk of the American league players? The list of possible fouls is currently very long. And the long description of all the special cases for "CB Fouls Only" is a bit ridiculous.
Maybe I should do a video on why the APA should embrace "No Ball Fouls." Just play and have fun. Don't worry about all the "silly" fouls called in other leagues like:
- CB touches with or without ball in hand
- double hits
- no rail contact after the hit with and without rail-frozen balls
- wrong-ball-first for close, near-split-hit shots
- push shots
- intentional miscues
- scoop jump shots
- cue lift shots (already allowed in the APA)
- driving balls off the table
- not having a foot on the floor during a hit
- not marking the pocket for the 8 (currently penalized in the APA)
- etc.!
What do you and others think?
