Attempting to DELETE a user through REST API returns '405 Method Not Allowed'

src/mailman/rest/docs/users.txt clearly states "The REST API can be used to add and remove users, add and remove user addresses, and change their preferred address, password, or name." When I send a DELETE request to either /3.0/users/1 or /<email address hidden>, I get a '405 Method Not Allowed' response.
