PWAs have limitations, yes. But you just mentioned how 2 of the biggest Electron users could not use Electron without sacrificing much if anything.

I think once you're in this other territory then you should consider full native instead of Electron. Why you choose to use an editor housed in a browser engine with tracking baked into the application is your decision. There are plenty of other native editors, both GUI and TUI, a user can choose.

Nobody chooses VSCode specifically because it's in Electron, we choose it because it's a good editor.

Any app can send network requests, so any app can incorporate tracking. This has nothing to do with Electron either.

But to your original point: yes, the more Electron apps that are really just web apps and can be gotten as PWAs, the better.
