It has not been near the top of the priority list. We have looked
at it and thought (more or less) "oh, that shouldn't be *too hard*,
but it looks somewhat annoying" -- see https://github.com/lme4/lme4/issues/6
If you want to chime in on the issues list that might help push the
priority up slightly.
