Can you add an explanation for why this is being reverted?

There was a cat on slack, the tl;dr is that the previous PR introduced a new default that brake loading of older models. The solution would be to save the fully materialized config to avoid it, but that would require more though so the quick fix is reverting and reintroduce this feature later

Test was fixed upstream.

Until we start saving the fully materialized config, there's an implicit dependency on whatever the default behavior is at the time of model creation. Filed #2066 to track.
