shrug Maybe. But maybe it wouldn't have made a big difference. Ultimately, the answers to those questions lie in documents that are probably SpaceX proprietary information--questions like the state of their supply chain, and specific components of Dragon and its software. Personally, I think it makes sense to have included the COTS-3 objectives as part of this combined COTS-2+ flight. If they can manage it on this flight, then it's a hundred million or so they don't need to spend. If not...then they're not particularly any worse off, other than a few months of lost time, and it's all work they would have had to do eventually.
