I wonder if handing over pass pipeline control to targets at

(either giving control back for stuff like final() or make it call

Perhaps, but not sure if such changes are desirable for stage4.
And certainly unsuitable for release branches.
That would seem to take a big mistake (machine_reorg) and make it even
worse.
