Good point, but that would still be welcomed, though I'd probably prefer it be a diffeent product (ala the opposite of react-native).
Flutter has shown that it's possible to build a truly native implementation from "web" tooling. I've shipped apps with Ionic and such before (but not React-Native yet), but despite how much care goes into the application, they've still never felt native, and Flutter bridges that gap perfectly.
If it somehow managed to also be able to deploy the same code to the web, perhaps using a different (or providable) CSS grid, I think it's as close to a holy grail as we'll manage.
