If there's one thing you can always count on in the Linux world it's that packaging can be a nightmare. The OBS Studio team are not happy with the Fedora folks due to Flatpak problems and threatened legal action.
I’ve made several Qt apps (in C++) easily packaged using AppImage. Perhaps OBS is harder because they require some level of integration with the hardware (e.g. the virtual camera perhaps requires something WRT drivers, I don’t know), but in the general case of a Qt app doing “normal GUI stuff” and “normal user stuff” is a piece of cake. To overcome the glibc problem, it’s true that it’s recommended using an old distro, but it’s not a must. Depends on what you want to support.
As a user, I prefer a native package, though (deb in my case).
