Review Comment:
   From a Power BI perspective, the most important use of cancellation is for 
Direct Query because users can generate a lot of queries simply by clicking 
around in a visual and in-progress queries will need to be cancelled if their 
output is no longer needed. DQ output tends to be relatively small, so being 
able to cancel in the middle of reading the output is arguably less important 
than being able to cancel before the results start coming back.
