It used to be that integrating similar apis was so easy, the usual way
   to do so seemed to be, unless you were closely involved with the
   designers of one of the projects, to actually start an entirely new one
   that superseded both.
   The issue with me doing that is that I would be likely to have a
   psychotic break when people wanted me to fix bugs they reported.
   So there's more return for me if I can get the existing projects to
   integrate or generalise.
   But the option is open, since it's all pie-in-the-sky.
