I've noticed a lot of smaller creativity/productivity apps are not available in distro repos. They're far too niche to get attention from distro packagers. However a lot of them are in Flathub and they work on any distro.
I find it curious you make that comparison about Pipewire because to me, Pipewire is just an incremental improvement for audio, not really changing anything on a giant scale. Most pro audio apps were already using Jack and got all the benefits of that type of system. Pipewire only makes it so they could connect to the odd Pulseaudio app, which is pretty rare. Not meaning to downplay it or anything. It is still a pretty good improvement, but its major contribution is what it does for video, not audio.
