Fair points all of them.

With the side car support we haven't faced any issues so far tbh (on windows and macOS).

Also I agree that the lack of wgpu is annoying. This is why for our cursor rendering (our sidecar) we are just using winit with wgpu. We are thinking of trying egui for our cursor rendering and then maybe try to integrate it with Tauri and remove the sidecar completely.

Our frontend is quite simple so we don't need wgpu there. Though I agree 100% that with electron you will have less surprises.

Hopefully our experiment won't come back to bite us and we will be able to contribute back to the community.
