This video describes a dumper / cloner. At about 5:18 it demonstrates Minecraft running on Linux via an emulator (he who shall not be named) on the Switch with better performance than natively on the Switch. I’m not sure if it’s Bedrock or Java edition. He also said the performance increases are across the board (I think or at least not limited to Minecraft).
I’ve played Minecraft on a ton of devices, phones, tablets, Switch, Steam Deck, Mac, PC. I think my best experience is Java on Steam Deck.
