not sure if the above reference to statistics is directly related
to your comment on sipTransactionTable below or not. if not, are there
other statistics that you feel fall into the category or
exposing far too much information?

i had similar feedback from others when support of the sipTransactionTable
was being considered by a project. the effort involved in supporting
the table was a problem.
we can focus some discussion on the viability of the table during wg last call.
i'd rather do that than to yank the table w/out further discussion.
at the very least, we can definitely make the table optional.
right now it appears to be in a mandatory group - which seem wrong to me anyway.
