The problem is that the bounding box included in the gpkg does not cover
all points: these missing 2 points are outside the bbox embedded in the
gpkg. As a safety measure, v.in.ogr applies a spatial filter using the
input layer's bbox to exclude corrupt features (previously observed in some
shapefiles). This spatial filter is passed directly to OGR and as a
consequence, OGR provides only 28 and not 30 points to v.in.ogr.

I am not sure what to do about this. Disable this safety check again?

is a gpkg file with 30 points and only one field as attribute. When I
import it into GRASS, either with v.in.ogr or v.import, I only get 28
points imported. No idea why. Meanwhile, ogrinfo -al reports 30 points,
same as QGIS
