Not likely:

I have not read the code of the solver, but solving YouTube's JS challenge is so demanding that the team behind yt-dlp ditched their JS emulator written in Python.

That's a great idea, but if they did, then YouTube could retaliate by specifically using features that MicroQuickJS does not support.

Of course... The arms race is eternal. :)

There's no reason it has to be lightweight, what it has to do is solve Youtube challenges without workarounds due to limited Javascript syntax.

Likely not, given that it only implements ES5.
