That is the sort of data analysis I am paid for in my day job. Broadly, your point stands, with the caveat that is not necessarily so much a dearth of options, so much as how niche and pointless so many of those options are.

That is why we have pathfinder 2.0 now. The Trap feats got so bad they became a swamp of trap feats and everyone had to start reading internet guides on how to build thier characters if they didn't want to be sub-optimal.
