Only if someone is interested enough to write them....  Actually,
I thought parametric GLMMs were an unsolved research problem in
general, even in, say, the logistic case.  I know there are
suggestions in special cases (and there is a glmm function in one
of Jim Lindsey's packages) but all the simple ones can be seriously
incorrect AFAIK.
