this seems to be either still an issue or a similarity to the one reported in bug 673520

There's clean solution.
dev-libs/light installs udev rules only with USE=udev.
Without this flag it could be co-installed with acpilight.

acpilight also could have same use flag.
For fast solution these packages could just block each other, but it may be more complex when more alternatives appear (e.g. blight).
Would be easier to maintain, if these rules were installed by separate file - but again I see two ways:

- It could be in dedicated category for udev rules.

- Or it could be installed by acct-group/video, which would get [udev] flag in proces.

In second case all acpi backlight control tools would require acct-group/video[udev].

This would be yet simpler if there were... I don't know, what best name for virtual package of such class. It would have this flag, while implementation ebuilds could completely get rid of this file.

Package with this rules file could have it in FILESDIR in order to keep SRC_URI pure.
