I am not part of TC39.
I do not really have any opinion on whether it's a good or bad idea, but
I have some questions (below):

What's your interest in seeing this happening?
What would be the benefit for you?
For the spec?

It seems like a good specification already (I can't see a copyright or
licence. What's the status on that?). And you have two interoperable
implementations apparently.
What more would you need from a standardisation process?
Reaching out more browsers to adopt it?

As much as I enjoy JavaScript, I'm aware of its limitations and I'm
looking forward to more languages compiling down to JavaScript and your
work is an excellent step towards having more of such languages, so
thank you :-)
