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.
