Josh Elser commented on HBASE-19770:
------------------------------------

[~appy], thanks for the feedback. It was definitely something that caught us by 
surprise at $dayjob. We simply reverted the behavior entirely for our testing 
framework.

I think flipping the default to {{true}} is something we could consider if this 
"experiment" is deemed not as helpful as intended.

> The {{list}} command should be returning {{\['a'\]}} but is not.
> The command class itself appears to be doing the right thing -- maybe the 
> retval is getting lost somewhere else?
