It seems that your approach matches the pipewire development policy
and the current situation.

From https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/FAQ#does-pipewire-r...

     Does PipeWire Replace ALSA?

     No, ALSA is an essential part of the Linux audio stack, it
     provides the interface to the kernel audio drivers.

     That said, the ALSA user space library has a lot of stuff in it
     that is probably not desirable anymore these days, like effects
     plugins, mixing, routing, slaving, etc.

     PipeWire uses a small subset of the core alsa functionality to
     access the hardware (It should run with tinyalsa, for
     example). All of the other features should be handled by
     PipeWire.

We no longer need pipewire-alsa.
