WASM sounds great in theory but it's so much pain in practice. Once as a presentation demo I made it run on ESP32 but in the process of digging deep into runtimes and WASM spec, I wanted to disclose pros vs cons and it killed my presentation.

I realize wasm wasn't designed for embedded but it made me open my eyes to it's intricacies like minimum memory allocation, why not native 1 byte variables?
