When two profile handlers don't agree on the current profile it's ambiguous what to show to the legacy sysfs interface. Add a "custom" profile string that userspace will be able to use the legacy sysfs interface to distinguish this situation.. Additionally drivers can choose to use this to indicate that a user has modified driver settings in a way that the platform profile advertised by a driver is not accurate.
