Justin Mclean commented on FLEX-33865:
--------------------------------------

For what it's worth the patch looks reasonable to me, if it came with some CG 
before and after screen shots I'd check it in. @Maurice no one is more senior 
than anyone else here and all checkins are commit then review. There nothing 
wrong with trying to improve a patch after it has just been committed. Worse 
case it can be easily reverted.

> ConstraintLayout / LayoutElementHelper are memory inefficient (and slow)
