Comment:

 Hi there, thanks for the ticket!

 Per the [https://make.wordpress.org/core/handbook/best-practices/inline-
 documentation-standards/php/#1-functions-class-methods WordPress
 documentation standards], `@return void` should not be used outside of the
 default bundled themes, so most of the core functions don't have that tag
 if the function does not return anything.

 There is an exception for functions like `wp_title()`, which can either
 return a string or display it, it which case they have `@return
 string|void`.
