There is a ton of work going into a Tauri based on CEF. https://github.com/tauri-apps/tauri/tree/feat/cef

My hope is this still acts like a library that multiple Tauri instances share. That would still have the upside of Tauri's shared library architecture (boo statically compiled programs, what a waste of precious ram!) while still letting us have a viable runtime. First app load might not be lightning fast but second app load is hopefully faster!! The OS webviews range from mediocre to absolute garbage; this to me would be a great improvement, that makes me happy!
