   > Overall, I think these changes are a good idea, however, this refactoring 
can very easily have bugs that are hard to spot. I'm not sure if this is the 
best for a 2.1 change, risking potentially introducing more bugs than the 
original PR set out to fix.
   
   @kevinrr888 I also like these changes and was a bit nervous about making the 
changes in 2.1.  Personally I would like to try to get these changes in 
(because they make things more consistent which will reduce bugs long term, 
also the current inconsistency feels really buggy) and review our test coverage 
around this code.  While reviewing this today I found a place I would like to 
add a unit test for RFileScanner.  More generally we may want to eventually 
have something like #5474 that covers the iteratorEnv in all the different 
scanner types (like 
RFileScanner,OfflineScanner,ScannerImpl,BatchScanner,ClientSideIteratorScanner).
  We could try to as much as possible to run the same tests across all the 
different scanner types.   For this PR I will try to run all the unit test w/ 
code coverage and see what the coverage looks like for the new code.
