I’d be more interested in knowing if someone had ported the ideas behind react in a cross platform language, rather than shipping a JavaScript engine with all your apps. Or maybe there should a JavaScript virtual machine in the OS itself.
As a very adopter of react, flutter tickles me the same way.
I have a proof of concept already, but it's not cross-platform so that's a major downside, and I don't think many people need the combination of (1) Mac-only, (2) lightweight, (3) using JS for the core logic, (4) using web views for the GUI. I just don't think there's a market for that.

and so on
If people are willing to download that much for an entertainment product, then it should be no surprise they are willing to put up with javascript in their work and personal productivity apps.
