One model needed changing: that callback is run in another order (now: Rails runs them in the declared order, not the reverse order, as before). One test needed to not require code on its own.
When we have run this code for a while, we can remove this Rails 7.0-compatible fallback code. The links in the code comment lead to where we need to change when we upgrade, one more time.
