I don't think that it's big deal, it will not be used by most major Linux distros anyway since they are all systemd-based and there is already precedence with xfpm-backlight-helper which gets executed as root through polkit.
Speaking of, could you just execute xfpm-pm-helper through pkexec instead of sudo in the same way it is done with xfpm-backlight-helper?
xfpm-pm-helper should probably disabled by default on Linux since distros either carry upower < 0.99 or they have upower >= 0.99 and systemd.
Finally it'd be nice to install all of these helpers under $(libexecdir) instead of $(bindir) since they're not meant to be executed directly by the user and clutter $PATH. Thanks in advance.
