The change is broken up into 14 packages already. I have
converted the change into changesets and am trying to make a set
of 14 anti-changes to apply to 7158. Not sure if this is still
reasonable if edgar wants to delete 7158.

There were a lot of comments on the change that a reviewer can
keep in mind.  A glance at each changed method is enough to
catch most bugs, and if 5 people did this, it would be a quite
confident change.
