At that point might as well make an app.
Offline is one of the biggest reasons to ship a full PWA. This is what service workers are for. The biggest reason to not ship a PWA is Apple barely supports them and you can't siphon as much user data if sandboxed in the browser.
I would LOVE if I could get a basic PWA from my bank that didn't have all of these permissions like trying to read if I'm rooted or not, location access, storage -- none of their business what I do with my device or where I am -- and I could still scan QR codes, check balance, do transfers.
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.
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.
