Copy'n'paste code has a high maintenance burden because corrections
need to be done twice (e.g. I don't think Table 92 needs to be
reproduced in the doxygen comments for the new open function) and it's
easier to forget to do that if some of the code is only
compiled/tested on a single, non-primary platform.

At the minimum we'd need tests adding to the testsuite for that new
functionality.
