wp_dropdown_users($args); function pulls all WordPress users into a dropdown list on posts, pages, custom post types, and even some plugins. This is problematic. With lots of users, WordPress admin stops loading when this function is called for sites with large numbers of users. Obviously, one could increase the max_execution_time and RAM in PHP to accomodate looping through all users, but it doesn't solve the underlying scaling issue WordPress appears to have.
Aside from commenting out code in WordPress core and plugins using this function, what is a possible future-proof solution? If there is a hook/filter for this, please advise.
