The point is more that things are likely to be relying on the current behaviour, for example CODECs that don't actually support 24 bit audio due to a power of two requirement but cope fine when you play 24 bit audio in a 32 bit timeslot. This creates issues changing things even if the new behaviour is in some sense better. This is one of the unfortunate consequences of DT.
