It's unavoidable: They need to be indexed for any query that specifies
a subclass. This is also the reason why you'll need composite indexes
in more situations. For example, MyModel.all().order("foo") can be
done with the built in indexes, but MyPolyModel.all().order("foo")
requires a custom index, because it translates to
MyModel.all().filter("class =", "MyPolyModel").order("foo").
