I agree that if we want to differentiate for programmatic purposes
(which is what Sakari seems to be talking about) it would be better do so
with a flag. But lets wait till we get a real use case for that before
implementing the flag.
In the mean time I think syncing up the strings with the kernel is a good
idea.
