There's more to pipewire than that. It's a different audio model, so I 
would say it probably does work better to use multiple interfaces. It's 
worked better for me in pipewire than with alsa_in/out at least. I've 
tried alsa_in/out, but it is a delicate process.

There are more benefits than the one I gave (like unified video 
support), but that was the one feature that really blew me away.
