   Thanks, @srowen .
   
   In the email thread, I don't make a judge on any of the cases. I collected 
and share our behavior to make a more clear communication way to encourage this 
kind of discussions. :)
   > given your email thread, I'm still not clear on the logic for reverting 
this one. 
   
   For the following question, 
https://github.com/apache/spark/pull/23043#issuecomment-450004873 was 
@cloud-fan 's decision comment on the original PR. That was the only one I 
found.

   I feel in the same way with you, but I also remember that we made a 
different decision in this type of issues. For me, this has been a political 
decision instead of a technical decision. And, if there was a reverting request 
on the old branch, we tend to accept it because we are conservative and afraid 
of any unknown regression and pipeline failures.
