This is meant as a starting point for future refactorings, right? In the long
term I would rather have a single definition for each method (it makes it easier
to grep, for example).

Fair point.  As an alternative I've ifdef'd their only usage and removed the
stub implementations, since they're no longer needed.  Let me know your
thoughts.
