plasma-pa vs kmix?

just curious but does anyone know any reasons for why I would want to install plasma-pa over KMix?

To me it seems like KMix should be the default nowadays seeing as it's built on Pipewire rather than plasma-pa with pulse, but maybe I'm missing something that someone might have insight on (besides backwards compatibility which is completely fair and reasonable)

Reason why I'm asking this is due to the archlinux package group plasma opting to include plasma-pa as a default whereas KMix is included in as a default for the group kde-applications
