Please don't include commented out code.

Done.

While device data definitely is not the correct place to put this enum (given
that we'll be getting rid of it), since the service does not exist yet I guess
this would be ok.  Nonetheless, please add a TODO comment to clarify that this
needs to be moved to the service once it's there.
