Why not?  Those counts are not either "tuple level" or "block level"
operations; the fact that the implementation sends them in the same
messages doesn't mean that there is any association in the user's eye.
Barring making a fourth GUC variable to control them (which seems like
overkill), I think it's a reasonably sane definition to say "we count
these if any stats are being collected".  Doing what you propose would
simply expose an irrelevant implementation detail to users.

I can't agree with you on that opinion, either.
