I think comparisons with desktop browsers will be interesting! I intend to make this configurable and let people choose browsers and browser versions, including desktop browsers.

Because they'd rather wrap it in Electron and farm system telemetry at that point.

PWAs work well on Desktops, you can install them on Chrome etc and they show up as native apps in Linux and Windows (opening in a chrome window, minus any address bar etc, at least). If you already have a PWA, I don't know what Electron would give you.

You can also ship PWAs on the Microsoft Store and allow Windows 11 folks to natively install them (for an example/shameless plug: https://homechart.app).
