Reach?
I believe tournament-regulation tables are 9’ x 4.5’, and I believe they allow for the use of a bridge in some cases where reach is an issue. But in most cases unless you just have a very tiny frame and short arms, most shots wouldn’t be a problem.
Since pool isn’t a physical contact sport like boxing, volleyball, etc., I don’t see any gender advantage at the pool table so the divisions never made sense to me for pool. It would be like having a men’s and women’s division in pinball tournaments. There’s no advantage for gender: man, woman or mentally confused.
That does not dismiss the fact that the “trans” thing is still ridiculous on its surface, but I digress.
