the whole thing with Nintendo backwards compat is interesting, like it sucks that there's no guarantee of 100% perfect compatibility but i defo think they were constrained, and their history (maybe not recently with NSO but in the Wii-Wii U era) of specially crafting emulators to work with their games and doing testing will definitely ensure that the experience is good without needing hardware. Which is really really cool.
