a solution to a problem most people don’t have
I’d say the timeless problem of “I just want to run this app, why doesn’t it work” is solved with Flatpak. People who can compile software themselves are the exception, not the norm. For an average user, an app store that “just works” is great. And for a developer, only being required to target one common runtime simplifies things.

Individual AppImages still highly depend on system libraries, I’ve seen them often fail to run on older distros, for example due to an out of date system glibc.
Flatpak is not owned by RedHat or systemd. You can use flatpak while avoiding systemd components.
