MicroOS is different in that regard. It switched from pulseaudio to pipewire
and updates are installed automatically in the background and must be
unattended.

If MicroOS had a different repo than TW, we'd just add the required obsoletes
to the pipewire-pulseaudio package, but that's not the case and they have to
coexist.

Other than the Obsoletes, the only way to avoid this is to do the usual
Requires: (pulseaudio or pipewire-pulseaudio) + Suggests: pipewire-pulseaudio.
That way only new installs get pipewire, but that's against the design of
MicroOS.
