Roll out changes of reusables and sync.

1. Should target a few repo (probably those owned by infra) to test and ensure all is good.
2. Clean up cruft (old pointers) from repos
3. Sync org wide

Start by identifying the reusable changes, old pointers, and a few infrastructure-owned repositories to use for testing. Review those repositories and determine how the organization-wide sync should be performed. Done means the selected repositories work, obsolete pointers are removed, and the changes are synchronized across the organization.
