Yes. It means whatever implementation we do has either lazy count, similar
to number matched, or we have a way to reach to the output
format and check its specific needs (something that would be useful for the
other need we'd might have, checking if the output
format has axis order assumptions... e.g., don't think anybody is happy
with us producing lat/lon ordered data in anything
but GML).

Yes and no, we have a sequence of pull requests that introduced counts in
GeoJson output format, so someone definitely
needs it (to the point they contributed code for it). Generally speaking,
counting is useful for anyone in need of doing paging.
But I guess it could be made optional with a new config flag, of course,
only for the formats where it can be made optional.
