Barry has spoken (later, in a parallel thread) to the effect that this
isn't a real problem "most" of the time.  But to me it seems like the
obvious ways are (1) to expose the whole API (as an HTTP collection
attached at the version number -- Barry says this is hard, though),
(2) to somehow ensure that client-side REST calls are transactional (I
don't think this is possible), or (3) to provide the client a way to
probe for an API that the server guarantees is a no-op, except for
returning SUCCESS or NOTFOUND.
