Review Comment:
@xicm this leads to inconsistency: some boolean args are `arity=0` and some
`arity=1`, which will cause confusion and won't be a good usage pattern.
Besides, this basically ties usage with default values: what if an option
default change from true to false, then we need to change arity and it will
break. Please avoid any usage change in this PR and only tackle the NPE
problem. As i mentioned, this is an existing problem and should be addressed
separately and with more user-experience consideration.
