Tauri is getting traction in the meantime.

A non-native UI has some issues, but also one clear advantage - it is easier to make a cross-system app with the same looks.

Tauri is a good way of packaging offline PWAs. It kind of sucks for building proper applications. The entire model for integrating with a local backend is just bonkers (no, I don't want my local application to pretend to be a web server - it's not a web server, I want to give you actual host bindings and share memory).
