One of the comments in the main thread says that the original vision for the fedora flatpaks was to be mainly for things that fedora wanted to have tight control and be preinstalled in their distros (Firefox, LibreOffice, GNOME and apps, etc...), which makes a lot of sense, but at some point it lost their original vision and started packaging everything under the sun.
In another comment someone says that most of the extra packages are maintained by a single person (more than 700), there's no way a single person can validate and test all these packages (or even use them).
