For a lot of uses you can go even smaller than Alpine. Static executables for example don't require standard Linux tools to operate. I expect WASI would be similar. Just drop the runtime and your Wasm files into a scratch container.
True. A static executable doesn't even need Linux in the first place, that can be done with a unikernel. It's a tradeoff about familiarity, size, performance, documentation and technical level.
