     * looking up users, thus returning the wrong subusers (or no subuser at all).
     *
     * For example, 12aaaaaa-bbbb-cccc-ddddeeeeffff would be cast to "12" if you tried to cast
     * it to an integer. Then, in the deep API middlewares you would end up trying to load a user
     * with an ID of 12, which may or may not exist and be wrongly assigned to the model object.
