Yes. This is cold hearted, but I would suggest that for those for whom this is too hard, they should reconsider exposing their machines and code directly to the public Internet.
Why should they reconsider it? Someone that just got into development and might want to show their friends or family something they are hacking away on. According to you they now need to learn about VPS, some random nginx settings or other SSH nonsense and meet some arbitrary "minimal" criteria you have decided upon because that is how you would do it. I think you should reconsider your acceptance of people that don't share your same technological expertise.
