The current spec suggests a much more complex rule. The conditions are
ignored if it can be speculated that the request-sans-conditions would
fail. It's more like:

first, perform the request without conditions
    if it fails, return the failure. (conditions ignored)
    if it succeeds, test the conditions
        if conditions hold, return success
        if conditions fail, *rollback* the work done in first step
            and return 416 or 304

It would be nice if it's simplified as you just stated
    conditions are tested before performing the requested method.
