That feature is kind of hidden, as the only place where it is
mentioned in the manual is at (elisp) Generic Functions

 -- Macro: cl-defgeneric name arguments [documentation]
          [options-and-methods...] &rest body
     This macro defines a generic function with the specified NAME and
     ARGUMENTS.  If BODY is present, it provides the default
     implementation.  If DOCUMENTATION is present (it should always be),
     it specifies the documentation string for the generic function, in
     the form ‘(:documentation DOCSTRING)’.  The optional
     OPTIONS-AND-METHODS can be one of the following forms:

So it is not official feature, as `defun' and `cl-defgeneric' are not
same and there is nothing about it explained in `defun' doc-string
