[R-sig-ME] Is anyone using the lmList() function in the lme4 package?

When we wrote the nlme package we tried to be very careful about
starting estimates and created the lmList function to allow evaluation
of coefficients from within-group linear fits. It turns out that it
is most useful for longitudinal data where there are enough
observations on each subject to do within-subject fits; that is, for
data like the sleepstudy data. Subsequent developments have made it
easy enough to fit the mixed model reliably without needing a lot of
preliminary work to get starting estimates. (Similarly, the
groupedData class was a good idea at the time but no longer
Would anyone miss the lmList function if it was removed from future
versions of lme4?
