You can see cases where people just don't connect some of the signals for whatever reason so even if the two devices could do bidrectional audio the board can't, and there are also cases like the at91sam9g20ek where the DAI is connected for bidrectional audio but there's not actually any audio inputs you can connect (even loopbacks) for one of the directions so it's best to just mask things out from the user.
