Sadly that's not the case. Many electron apps are written with a single version in mind and that version needs to be treated like any other dependency. Knowing you are targeting a single platform lets devs aggressively optimized that platform. Also, some electron apps will modify the "browser" part. As for download sizes, aside from the first download all updates can use Delta update packages and I believe this is built in. Re memory usage, with sandboxing the way it is today I'm not convinced you would save all that much memory unless you were running over 10 different electron apps, and even then compared to the total memory usage I feel it would be insignificant enough to not warrant the "JRE architecture". I don't really have anything to back this up, its just a hunch.
