We don't use SHOW CLIENT_STATISTICS at our place.

We don't use SHOW INDEX_STATISTICS either.

We *do* use SHOW USER_STATISTICS (but haven't used SHOW
TABLE_STATISTICS yet ...)
We modified our patch so that SHOW USER_STATISTICS displays Cpu-time
as a DOUBLE (since it is already a double internally). It also shows
Rows_examined (in THD as examined_row_count and
diff_total_examined_rows) for each user ...

I'm not exactly certain about the origins of our current userstat
patch. (My boss gave it to me back in November--when he hired me). I
*think* it is an original Google patch, although some of our boxen are
running a Percona-derived patch ...)
