My mental model of how this process works is that when YC evaluates your startup you are starting at zero. It is up to you to sway them to a one. If you were rejected, that is because you didn't sway them to a one. It is probably a variety of factors, and each of those factors could have been overcome by a number of things. YC would have to work backwards and figure out what it was that didn't get them to a one. Why is it up to themn to do that work for you? Also, if it was just one thing and they could put their finger on how to fix it... you probably wouldn't be rejected.
