Yes, but on the other hand you have methods like this one in java.util.List:

public void add(int index, Object element)

I can't say I find the collections API to be incredibly consistent
about return types. When we arguing similar points in JDOM, I noticed
that all sides of the debate could find justification for their
position somewhere in the Collections API. :-)
