This was already discussed (--> mailing list archives).
I (and others) find it more informative to get a feeling about
the size of the index (rather than the number of indexed objects)
in the overview.

It would essentially change the "number of indexed objects" (and
make it a bit more informative when one is interested in the size
of the index) ;-)
You must be a bit careful with the "non-zero".
Some indexes interpret (some) zero values in a special way, e.g.
"DateRangeIndex". It interprets "None" as "no limit".
However, I agree with you: at least when an object "o" does not
define a value for index "i", then "i" should not index "o".
I would also prefer when "None" would consistently means:
I do not have a value (in the current context).
But, this will interfere with some indexes.
