This seems like good news.

The babbitt and backing materials are very much softer than the crank journals. The crank journals are properly heat treated and surface hardened. They are really quite tough.
If the bearing does not actually spin in the rod, there is a good chance the crank will be just fine even if the bearings are quite bad.
