Yes, you do. Shipping quotes are now using Workflow-ng, and the shipping quote methods need to implement hook_configuration() to be useful. Take a look at uc_ups_configuration() and uc_flatrate_configuration() for examples of the minimum requirements. uc_usps_configuration() shows how to use conditions on two different methods. These configurations are set up as defaults, so users can change them as they need to. Mostly this will be adding conditions so the quote is calculated under specific circumstances.
