I asked:

Could someone provide the use case for this feature and why it should 

What capability does having parameters at all for update give the client 

I really would like a concrete example we can discuss - the test cases 
tried to explore this.

I see several interpretations of parameters:

1/ dataset is fixed at the start of the update request and the same is 
used for all WHERE clauses regardless of USING etc and of operations 
earlier in the request.

2/ The dataset structure is fixed, the contents of the graphs can change 
across operations within a request.

3/ The dataset for each operation is modified in some way by the params 
so it's the combination of the graph store and parameters that matters. 
  Graph created by earlier operations in open request are visible in the 
dataset of a later operation.

These are not independent and there are popssible variations.
