Most Flatpaks depend on the Freedesktop Platform runtime, or GNOME/KDE runtimes, which are derived from it. This contains several hundred common dependencies and librarires programs need, like gcc and python. When you update the runtime (change it from 22.08 to 23.08 in the manifest), all the dependencies are updated too. Many simple applications don’t depend on many more dependencies than are available in the runtime. Some…have more complicated dependency trees.
But counterpoint: the developer will update the dependencies when they are known to work properly with the application. Upgrading GTK3 to GTK4 in the GIMP flatpak will just break the application. Same thing with Krita and the dozens of patches to libraries it depends on. If you upgrade the application in the name of security before it’s compatible, all you end up with is a broken application. Which I guess is more secure, but that’s not helpful to anyone.
Which means that if you have a flatpak with an uncommon library and the dev stops issuing updated flatpaks because they get hit by a bus, you could be SOL with respect to that library. Distro libs are less likely to have this happen because very few distros have a bus factor of 1—there’s usually someone who can take over.
I wonder how much work would be needed to make a “FreeDesktop Linux” complete OS, with the runtime + whatever it needs beyond that. Then when you install a flatpak, it’s just like installing, uh, I didn’t think this through tbh.
Well, if you think about it, the Freedesktop Platform is essentially a distribution. And Flatpak used to be called “xdg-app”. If you’ve got all your graphical applications installed via Flatpak, with GNOME, Systemd, glibc, GRUB and all the core dependencies only packaged for the base system (essentially Arch’s core repository), that’s pretty much a Freedesktop OS.
Hey, maybe we could use Snaps for the base system and Flatpaks for the userland? Or are these the kinds of ideas that get people stoned?

Thanks for the interesting point! I learned something today. I guess it all depends on your use-case, whether flatpaks make sense or not.
