Is there any reason why we cannot put a pipewire-with-aac build in the nonfree repository that replaces the default pipewire build using the Alternatives system

Is there any reason why we cannot put a pipewire-with-aac build in the nonfree repository that replaces the default pipewire build using the Alternatives system? Or perhaps pipewire could ldopen() libfaac as required. Edit: the issue is social, not technical—it’s not desirable to have an easy way to “slot in” a nonfree aac because of patent disputes
