I can't really tell whether the Key<?> change would be an issue for you - it
would depend a lot on how you are using namespaces and how you generate keys
(remote java client?  gwt?  server-side only?).  If you're using the
"standard" practice of setting namespace *immediately* in a servlet Filter,
you shouldn't notice any difference... but if you are manipulating
namespaces in a more complicated way, it's hard to predict.  Namespace is a
transient field in the native datastore Key, so it behaves... strangely.
