The default behaviour appears to have been changed. If you provide the /syncOnly parameter it preserved the old behaviour for me.

 /syncOnly                          - Generate only synchronous method
                                  signature. Default: generate synchronous
                                  and task-based asynchronous method
                                  signatures.
