Interesting. I would normally expect the GeoTools datastore to handle this
- but you are correct if you can tell up front that there is no data in the
provided bounds you could avoid instantiating a datastore completely.
A couple of notes of caution. Lat long bounding box is fairly lax, you may
find it more accurate to project the request into the native projection and
check against the native bounds.
