An official appimage is planned, but in the meantime I personnally trust @andy5995 We also made the flatpak official just a few days ago.
It's as native on Windows than it is on macOS, BSD, Haiku and Linux. It's just that the distribution of the most performant version is a bit slower on Linux it's out of our control. We could wait for the maintainers to release but then just like when the trailer leaked, we'd get confusion in the lobby if they take 3 months like A26.
