This summarizes the change in behavior well.
The old way allowed updating to null while the new way keeps the state value if removed (UseStateForUnknown behavior).

This is why we need the ImportStateVerifyIgnore: []string{"delete_on_create_timeout"} in import as it will not be present in the state after import.
Because once the value has been used in create it remains unchanged.

Note: A fresh import and setting delete_on_create_timeout in the config will raise an update error saying it cannot be updated.
