It seems more like hardware breakage we're trying to fix than a feature
- it's not like it's adding something we didn't have already (like
setting a time in an alarm where the alarm is an additional thing), more
just trying to execute on an existing user interface successfully.  I
can see that there's a case that it doesn't map very well onto the
standard interfaces so perhaps we have to add something on the side as
the hardware is just too horrible to fit in with the standard interfaces
and we have to do that.
