In Linux, everything is a file. In Pipewire, everything is a "node"... everything!
Pipewire has mature to a level of stability as it moves to consistency across releases.
Now the prime issue has elevated to which visual manager will come out on top. There are some very neat ones and I hope the 'EASIEST" to use wins over size. The concept that Pipewire brings is 'revolutionary', the easiest to understand in use, will only speed its adoption.
Pipewire, essentially, collapses 4 past audio subsystems into a single Linux subsystem for simplicity in both concept and use.
The visual managers contending for clear understanding and use:
QJackCtl
WirePlumber
Carla
VOICEMEETER
3 videos have surfaced in past week on youtube that are excellent for Pipewire.
It is hoped that PUP developers will make this easy and simple to understand, universally.
