The configuration governs the creation of the inner table objects (e.g. naming autogenerated indexes). Setting the configuration on an existing table, once some of the inner objects may have been created, makes little sense (the objects may need to be regenerated according to the new configuration but this isn't currently implemented).
Besides the maximum identifier length, the table configuration will contain other parameters in the future. Changing them on an existing table will also make no sense.
