Just because you don't feel the weight of electron apps, it doesn't mean it's not there.

You just have a powerful computer.

I switched from Slack / Discord to Ripcord and, even though the UI is not great, it's much cheaper to run. It's using 80mb of RAM with multiple slack organisations open and multiple discord servers.

Pritunl written in Electron is using more than 100mb or RAM, just to let me provide 2 factor auth and connect to my VPN.

I've been toying with the idea of writing a native app for Pritunl, but I don't work for Pritunl and I have 32GB of RAM. I'd love to rewrite Visual Studio in Qt, but I don't work for Microsoft.

The funniest thing is that the developer experience on Qt is years ahead frontend development in the browser and it's been like this for more than 10 years. You have a mature widget system and you even have native looking widgets.

I can see the appeal of Electron; if all you know is web development, you don't want to take the additional complexity of learning a new framework. Personally, I would definitely use Qt.
