Comment:

 I understand the concern is that the string or array passed to this
 function does not have to be a valid callable, hence the suggestion to
 change the docblock to `callable|string|array`.

 For example:

 {{{
 remove_action( 'foo', 'this_function_may_or_may_not_exist' );
 }}}

 The above is valid use of this function even though the `$callback`
 parameter is not a `callable`.
