Making it more difficult to enable the alternative functionality
wouldn't necessarily make the list any more comprehensive, it just
raises the bar for users who want to try to help.  If users report the
bugs to their distros, distros will help to forward them upstream.
You can't expect to fix a social problem here just by making it more
difficult to fix the original problem at hand for individuals.
