Ted, I've searched for a definitive reference on this but nothing turned up quickly. However, every reference I did find specifies that the EOF is written for SMS Managed Datasets.
A DATACLAS can be used by both SMS and non-SMS managed datasets, but a dataset is not SMS managed unless it has a STORCLAS and ultimately gets allocated to an SMS Volume. So I'm led to believe that the presence of a DATACLAS does not cause SMS to write an EOF when allocating a non-SMS dataset.
