I can't speak to that directly, but I would like to advertise Taylor Campbell's write-up of the issues, which I think is excellent. The problems with the R5RS names is that they are basically Maclisp names that escaped the Great Renaming, perhaps because they were inadequately analyzed at the time. I haven't tested it, but I bet there are lots of implementations that get the edge cases wrong. R6RS replaced both names and functions, but the results are still highly irregular, and people don't have a clear idea of which one does what.
