PS: I hope that this is really better than electron because I hate all electron apps and the desire for many developers to use it to deliver multi platform apps. It is buggy, resources monster and doesn't work consistently.
It's not such a big deal if you're doing something akin to a typical web-app, but if you're doing something very unique the little inconsistencies across browsers can be an annoyance that isn't worth dealing with.
In contrast, Electron will "just work" and can be deployed pretty far back in comparison.
The rest starts to get philosophical: on Linux, BSD, or other libre OSs, these WebViews do get upgraded for usually a devices entire lifespan (unlike Android) and users are usually more confident in their OS's update system and maintainers to regularly do updates. Of course, you could always make it purely a PWA and pressure the likes of Mozilla to actually support hosting these sorts of apps for OSs (RIP SSB).
