Hello folks Humbly stepping in: I believe that if there is support for multiple geometries (and thankfully there is!), then all such geometries should be considered for every operation when the user has not specified anything.
In fact, I have noticed that this is indeed the behavior implemented in SimpleFeatureImpl.getBounds(): it checks all geometries to compute the feature's bounds. On the other hand, this is NOT the way things are implemented in MemoryDataStore.getBounds(): it could have just asked for each Feature's bounds, but for some reason it computes the bounds explicitly using only the default geometry. In my current view of things, this would be considered a bug.. Other than that, I don't really know how things behave for other DataStores - if my current view is correct, I hope that they all consider all of the geometry attributes :). Taking a quick look at JDBCDataStore, it seems to be the case.
