 At present, Its impossible to filter an option being updated, While there
 is an action which can be hooked to notify the option has changed, it
 cannot be modified directly.

 Attached is a patch which adds 'pre_update_option_<option_name>', It can
 be used in combination with a filter on get_option() to seemingly hide
 various portions of options to the rest of the WordPress admin (or theme,
 etc), and then add them back in if the option is modified.
