 Replying to [comment:6 arena]:

 > do_action() should not pass '''any''' argument if not required.

 See #14881 - Unfortunately removing this would cause 10 years of back-
 compat issues.

 If you have an action to hook, and don't intend for it to receive a
 parameter, but it has a default value for it's first argument, pass `0` as
 the number of `$accepted_args`.

 If the root cause of this ticket is `do_action()` passing an empty string
 by default, unfortunately this is a duplicate and it's not something that
 will be fixed/changed in WordPress.
