Yeah, that was my impression too which is why I passed on it and went with Tauri instead. Which is not to say that Tauri perfectly map to the boxes I wanted checked, but beggars can't be choosers
Tauri and Dioxus both share a webview and all of Tauri's extensions/plugins work with dioxus, so the only real difference is where your code lives. Since Dioxus and Tauri share a good deal of architecture similarities, it's not really an "either/or" case and I'm sure whatever the Tauri folks try to monetize will work with Dioxus apps automatically.
IMO if you're building an app in Rust, you probably want to avoid the wasm build step and shim out to the little bit of JS here-and-there for interactions you can't quite get in Dioxus.
