The earlier the better if I had a say.

That's what I feared.

How would the inability to automatically track changes of an imported  
object "give a better experience"?

It does simplify things, even more so, it over-simplifies them.

Well, this wouldn't necessarily preclude optionally tracking objects,  
an activity would have to be prepared that the object may not be  
available, and in this case just continue to use its own copy.

In summary, this means that the majority of the datastore API will  
not be available to activities. When can we expect a finalized API,  
with documentation what operations will be allowed?
