I think this has actually made the release process harder by leaving the unsupported image streams in whatever state they are in. Any changes in the library will never get reflected, leading to bitrot, which is what has broken OKD for all releases. trying to remove the unsupported imagestreams turns out to be very difficult because there are tests in various places expecting them. We should either remove the ticking time bomb that is leaving things in an indeterminate state that may change out from under us, by removing any imagestreams that are unsupported and dealing with the CI fallout, or we need to keep syncing all things from library.
