Well my particular interest is edible plants that are roughly native to my region, and it turns out there's just not a huggee selection of beans in that category? There's a couple Strophostyles species here that are tastier as faux green bean pods than they are as dried beans. There's at least one native Lupinus whose edibility is even more questionable than the Thicket Bean, and likely requires weeks of brining. There's Amphicarpaea bracteata, which is easily the tastiest AND simplest of the bunch, but culinarily they're really more akin to peanuts than pintos. There's Apios americana, which has DELICIOUS tubers, but it doesn't really super want to produce beans even though it can. Finally, there's Desmanthus illinoensis, which... actually that one's very productive, easy to grow, AND easy to prepare? Honestly I should have just stuck with that one lol.

My hope for all the complicated ones is that, once a process is ironed out and simplified, it'll get easier? We'll see. Just trying to do my part to broaden the number of species humans subsist on really.
