The SDUC spec expects CMD22 to get squeezed between CMD23 and the read/write command, e.g. CMD23->CMD22->CMD18 and CMD23->CMD22->CMD25. At this early stage of adoption, we want to avoid an amid stream of fixes & quirks of bogus hw, that tends to apply extra logic specifically around auto-cmd12 & auto-cmd23. Let's leave close-ended out for now, and re-consider this should those cards become ubiquitous, if any.
