Then you should call it
"completely reproducible binary builds for binary patch"

I think perry@ has/had some idea about it.

To implement such a new infrastructure, we need the following process:
(1) describe your purpose or actual problem to be solved
(2) mention your idea how to solve it
(3) design it and request comment
(4) implement it and call for review

It looks you are just saying about (2).

You don't mention your design at all, so I can't comment about your idea.

Where should it be handled?
By targets? rules?
Scripts under src/distrib?
Local scripts as used on releng servers?

I'm not asking policy, but your idea of design for your purpose.
