New Package Format - AppImage / tar.gz

I occasionally use different OSes than the ones that use APT or RPM (and Snap is too slow and clunky), is there any availability to distribute Brave as an AppImage which would allow installation on basically any Linux distribution. Alternatively including the binaries in an extractable package that is self-contained and updates itself would also be helpful.

Without a universal way of installing the package (and not having to go to great lengths) it’s easier to just use something else.
