For anyone not on board because of how the WebViews work, or that it uses WebViews at all, the roadmap has other renderers to be explored. I believe the majority of the Tauri framework is decoupled from "web" and it's merely supported first - likely through popularity.
When WebView2 goes multiplatform, you might even be able to use it on every platform (if you like web, but want a consistent browser engine on each platform)
I'm more interested in where Tauri will go next in terms of support - not where it is on day 1.
