If we have a better substitute, I think there'd be nothing wrong with
removing those features. They were never anything but pretty crufty
anyway, and they are *not* a compatibility issue because applications
have no direct way to access those stats. However, you'd have to be
sure that the substitute covers all the use-cases for the old stats
... which strikes me as a lot more territory than this patch has
proposed to cover.
