Comment (by jlambe):

 I was going to report this as well and I found this original issue on
 trac.

 Just to go against the title issue, I suggest that the call to the
 `add_filter( "sanitize_option_{$option_name}",
 $args['sanitize_callback']);` (options.php - Line 2026 - WordPress 4.9.6)
 does define the 3 arguments provided by the `apply_filters(
 "sanitize_option_{$option}", $value, $option, $original_value );`
 (formatting.php - Line 4314 - WordPress 4.9.6).

 Indeed it is quite useful to get the setting name and it would make the
 code cleaner I suppose for some sanitization and validation on the server
 side.

 +1 to finally get this one merged on next release please :)
