Well, the lack of such a specification is a documented bug (see the FAQ on bug reporting), and I think everyone agrees it would be useful, just not as useful as what they would have to stop doing to write it.  In fact, such a document may well have a higher priority than it deserves: people who would want that sort of documentation are overrepresented in R-core compared to the general R user community.

There was a panel talk at DSC2005 (yes, four years ago) on the possibilities for a joint R/S language standard. That would have provided an external stimulus and a framework for finding all the inconsistencies. It didn't really eventuate.
