These metrics have been useless from the very beginning and are not very descriptive. If you like to get some meaning in your statistice, use vmstat. This is more costly, but actually shows something about the performance of your system.
Maybe we could concentrate on exporting these metrics instead buffer/cache and provide dummy metrics for them. At least "buffer" can be made to sth. like "shared" does now.
