Just to clarify, I think we are just proposing the removal of the enforcement of the stacking order. We will still allow multiple non-replace patches to be applied. We just won't enforce which patches can be disabled/removed at any given time. So I think your old way of doing things (individual unrelated patches on top of a cumulative patch) would still work. -- Josh
