Review Comment:
   Setting `HasSeed` has two possible indications:
   - Using same seed can have reproduciable outputs
   - Using different seed can have different outputs.
   
   However, our implementation does not provide reproduciable outputs due to 
the complexity of reproduciable distributed sampling --- We always provide 
different outputs in each run. As a result, it seems meaningless to provide 
`HasSeed` here.
   
   If we add `HasSeed` now, we may mislead users. However, we can add `HasSeed` 
later if we can provide reproduciable distributed sampling.
