/**
 * StarterTheme TODO: FIXME:
 * In the old days, when updating an address, we actually:
 * - checked if the address was used by an order
 * - if so, just mark it as deleted and create a new one
 * - otherwise, update it like a normal entity
 * I *think* this is not necessary now because the invoicing thing
 * does its own historization. But this should be checked more thoroughly.
