Also note the patch, to the best of my knowledge, was not ping'd.  As a
regression (and a P1 regression I might add) I would have expected Steven to
ping the patch and/or Jakub to have pushed harder for reversion of the original
patch which caused the regression per our patch reversion policy.

Either way it was not handled well. 


WRT on-the side datastructures.  The on-the-side structure here is the existing
tree structures.  At some point all the linkage between RTL structures and tree
structures needs to be sorted out, but I don't think now is the time nor do I
think the amount of usage here justifies using a precious bit in our base rtl
structure.
