No idea about most of that.
But arch rolled back the addition of
replaces=('pipewire-media-session<=1:0.4.1-1')in version 0.4.10-3 of wireplumber https://github.com/archlinux/svntogit-packages/commit/5e376fd9730d7b2aa77c40093a004bade9046e96
and therefore the Artix build followed suit. At least I think that what happened ?
So you can reinstall pipewire-media-session if you wish and not be troubled by pacman keep wanting to replace it with wireplumber. For the time being at least until they decide to revert the revert ;)
I guess it's not just me that has various issues with wireplumber ?
