Yep, seems something useful and would put geojson on par with the GML
output in this respect.
I'm wondering, does the GeoJSON format has a concept of a feature count, or
would it be some GeoServer specific extension?
The other thing that we'd need along the patch is a test (or a modification
of some existing tests) checking the
feature count works as expected (both today, and in the future as other
people modify the code).
Cheers
