Another use case, observed in the wild:

   - An library function is written to take an arbitrary number of
     positional arguments using *args syntax.  The library is released,
     presumably creating dependencies on the specific signature of the
     function.  In a subsequent version of the function, the function is
     determined to need additional information.  The only way to add an
     argument is to use a keyword for which there is no positional
     equivalent.
