Tauri's cef-rs is indeed quite good. I think it's available, ready, works: it's just that there aren't many folks using Tauri and only a fraction of them are aware/interested in exploring further. https://github.com/tauri-apps/cef-rs

Huge fan, this should definitely be the default. The user experience is incomparable.

One thing I'd like to verify: can the OS effectively use shared mem for cef across multiple different cef-rs apps? I really hope so. In this time of RAM being scarce, this optimization could be such a benefit.
