That is quite promising at least for my particular use case as I have spent many many nights trying to force a solution in which I wish to extend the functionality of my site, in a consistent UX whether web or native, that is outside of the modules that are currently available from UNA or Third parties and not possessing the time or likely skill necessary to build my own custom modules, I feel like PWA's filled that gap for me but over the many many nights its just been a pile of failure from UX to expected functionality in part because of the current limitations.
