So it took them nearly 5 years to fix fcitx in Jewpak.
And that's still nothing, there are even 7 year old issues that remain open to this day (https://github.com/flatpak/flatpak/issues?page=34&q=is%3Aissue+is%3Aopen).
Some other problems: https://flatkill.org/2020/ and https://flatkill.org/

The game devs who created SoystemD, Gnome, dbus, and of course Red Hat.
Seriously, this is the centralized package distribution platform you want to trust!?
