How is it possible, that Signal still only provides a .deb package and no .rpm, or even better AppImage or Flatpak? There is an unofficial Flatpak but is it secure?

I just read through the unofficial Flathub Flatpak for Signal and it is very simple. It fetches the .deb from Signal's website, installs it in the sandbox, and uses a launcher script to tell the OS some basic toggles like should it start minimized or should it display a tray icon. In the script it makes use of zypak, which to my understanding is to tell electron (chromium) to allow sandboxing to be handled by Flatpak. Here is the repo and the build instructions is the .yaml file.
