If we forget about the pain that most WASM toolchains happen to be.

MicroPython, like most BASIC interpreters in 8 bit days, also allows for inline Assembly.

As for running bytecode on MCU that is as old as MCU themselves, wasm doesn't bring anything to table.

You can actually opt-in to native compilation on a function level so it's not just a bytecode interpreter. You can also compile it yourself with additional functionality written in C/C++ and just use Python for the glue that isn't performance sensitive.
