Keeping to oncall sounds good for now. Let's wait til after code freeze to propose formally handing off to community.

One question for followup: is there some way we could have merges of just these autobump PRs alert to slack?

Someplace to see all deploys and all config changes pushed to prow.k8s.io sounds like a good followup that would aid troubleshooting.

But being able to filter down just to "big PRs that change a lot" matches the current experience people are used to. I'd rather not take away what they're used to before having something better.

SGTM, I do think we should relieve test-infra oncall of being concerned with these though, the community should be maintaining the images we test with in k8s.io without depending on the google infra oncall (see: recent go1.16 bump being in a bad state while people just waited for the oncall to upgrade ...)
