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.
