If the option being customized is a set (`repeat') of key definitions
(bindings), then that is the unit of reverting, IIUC. 

Only the object of customization can be reverted to its default value, just as
only that object can be set or saved. Pieces of the object are not individually
subject to these operations. To be able to set, save, or revert a single key
description, it would need to have its own defcustom. AFAIK.
