The recent "wide range MTB FD" thread provides the most recent example of a common issue. Front derailleur cable pulled is varied and there does not appear to be a reference for interested parties. Has anyone seen a front derailleur (and shifter) database?

I periodically check and haven't seen one. I have many modern standards to measure and document, but my interest remains low. It would be nice if the work has already been done, even if only partially. As it has been for RDs, casettes, and shifters.
