Pipewire recommends using the pulseaudio API anyway, at least for now:

https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/FAQ#what-audio-api-do-you-recommend-to-use

Which makes sense. Pipewire is supposed to be a drop-in replacement for 
both pulseaudio and jack. And both of those aren't dead. It makes sense 
for applications to try and work on any system, regardless of whether 
pipewire is used or not.
