Perhaps you don't consider that today we don't attribute contents
and use converters to "fix" them. Or maybe you really have crappy
geometry all the time (something that will make JTS throw exceptions
during geometry construction).

We have no exceptions there either:
public interface FeatureCollection<T extends FeatureType, F extends
Feature> {
...
FeatureIterator<F> features();

}
