But it's asking a lot more that than your typical accessibility setting. I appreciate difficulty choices but I don't expect devs to do it every time.

And if part of a creator's vision for a game is that it's brutally difficult, then i can understand them not even wanting to put in an easy mode even if it's technically feasible. At some point you're asking a sports car to be a pickup truck. There are more games out there than can be played in a lifetime; if one isn't for you, play another one.
