Why don't more languages offer flow typing?

Yep. Except that the base semantics of the language really are tuned for JavaScript. So I can't see a separation being feasible between the two.

It would have to be a new language, sharing maybe 90% of syntax etc. but differing in some places where interoperability with JS has forced compromises (base number types is one thing I can think of. I'd like separate int and floats, etc.) and, yeah, targeting WASM etc. And honestly, I'd be game for that. Esp if it came with performance advantages.

What you're describing is essentially the origin story for Dart.

Yes that's what I meant by proper type system - int, float, decimal... proper date/time/timezone support. To name a few :)
