So:

- The initial version was released over a year ago (3 month is the most recent patch release of the stable version).

- It is part of the Dioxus project (https://github.com/dioxuslabs/dioxus) which has been going since 2021 (but the other renderers are web/webview based).

- The native renderer (https://github.com/dioxuslabs/blitz) has been under development since December 2024 (building a whole new web engine is just a big project).

You're ultimately kind of right that it's not as established as 1-4 in the list. But I think it justifies it's place with the other frameworks lower down the list as one of the lesser-known frameworks that compete technically with those further up the list.
