Sorry for top posting, but exchange....
Automation is our friend. Define the structure/naming of the release repo patches such that when they merge, they auto generate the governance patch and submit it. It gives you time to run a cycle and see how things work and what a more elegant solution might be.

If we look back at the goals driving the change, this solves the
"temporarily bypass governance values" need. The main drawback (to me)
is that we continue to consider deliverable types and release model to
be a "governance" thing. Another drawback is the additional work needed
to sync changes back into the governance repo (see Tony's question).

Devil's advocate, we could copy over the type/model values from the
previous cycle as part of the new cycle opening, and have list-repos
work all the time. That sounds like less work than tracking the
retrosyncing of each and every override back onto the governance repo...

That's a one-time work, so I don't think having to do that is unreasonable.

It feels like extra work overall. More work for teams (having to file
two separate patches) and more work for us to make sure that governance
patch is merged, doesn't slip through the cracks and doesn't introduce a
drift between the two repos.
So... not convinced :)
