The rework could be done afterward.

Please don't go there. The usual approach is to

   1) Rework existing code in a way that the new functionality can be added
      with minimal effort afterwards and without creating API horrors.

Thanks a lot for the advice.
It makes things even easier for me, as I can start the rework, while the 
discussion on the actual write-rare mechanism continues.
