Applications doing audio (or MIDI) I/O should not, in general, be using any API provided by pipewire itself. So there's really nothing "to support" unless:

* you're a distro provider
* you're creating control and configuration apps for audio/MIDI on Linux
* you're working on a very unique application that for some reason needs to use Pipewire APIs

Unlike the Wayland/X11 situation, Pipewire intends to fully support existing APIs (ALSA, JACK, PulseAudio) and does (fairly well!)
