This is turning to "Linux for desktop" really fast. Or really slow depends how you look at it.
Even the web does not look like the web anymore. I am not even sure what do you mean by "the solution will inevitably be the web".

If you think that nobody will want to develop half a dozen versions of the app natively, why do you think they will want to debug PWAs on half a dozen OSes?
