Good catch Lars, I've put a notice at the top of our default
file that customizations to it will be overwritten, and to use the
directory instead.

For reference from the sudoers manpage:


     The #includedir directive can be used to create a sudo.d directory that
     the system package manager can drop sudoers rules into as part of
     installation.  For example, given:

         #includedir /usr/localetc/sudoers.d

     sudo will read each file in /etc/sudoers.d, skipping file names
that end
     in `~' or contain a `.' character to avoid causing problems with
     manager or editor temporary/backup files.  Files are parsed in sorted
     lexical order.  That is, /etc/sudoers.d/01_first will be parsed before
     /etc/sudoers.d/10_second.  Be aware that because the sorting is
     not numeric, /etc/sudoers.d/1_whoops would be loaded after
     /etc/sudoers.d/10_second.  Using a consistent number of leading
zeroes in
     the file names can be used to avoid such problems.

     Note that unlike files included via #include, visudo will not edit the
     files in a #includedir directory unless one of them contains a syntax
     error.  It is still possible to run visudo with the -f flag to edit the
     files directly.
