You bring up a good point.
Me and a guy were discussing this earlier in the week and the compromise we came to was that they need to have some sort of button to play with QoL improvements or not to. Best of both worlds. I'm purist with a lot of my old games and I only want the game to run better on modern hardware. But otherwise I love the clunky menus, the mismatched resolutions, and all the old quirks that came with the old games.
So yeah, a button. That doesn't seem too unreasonable to me. A decent middle ground.
