I think it does make sense to add Pipewire. Apparently it gains popularity.

The main advantage of Pipewire is its interoperability: It allows you to 
connect apps with each other that only support a specific audio system. Say 
one app that only supports JACK, another app that only supports PulseAudio, 
another that only supports ALSA and so on. So it tries to provide a universal 
plug on a system for all.
