For better or worse, it's holidays in the states. Very amusing for me being in a non-Thanksgiving celebrating country.
In addition, it's not a problem. The complaint is valid. Probably no one has coded up the right solution yet for comparison. I can't recall if one would want those statistics for a binomial random effects model, but I do recall some issues with model comparison in that setting, though they are a bit dated (say, 2 years or so).
