YES! Absolutely yes to this. Right now the built in language was made well before WASM was even a thing, but at some point in the future I'd like to make it target WASM directly or even potentially use AssemblyScript or something like it. I certainly also want to have the engine support importing WASM modules as plugins, for when you need serious near-native performance rather than a scripting language.

Tiny modules also sound awesome. I'll give the article a read, thanks for this!
