I do agree with what you are saying, but for a complete beginner, and a very general overview, I didn’t want to complicate things too much. I personally run my own stuff in containers and am behind CG-NAT (it’s why I gave it a mention).

That said, if you really wanted to give the new user that advice, go for it. Rather than just nit pick and do the “but actshuly” bit, start adding that info and point out how the person should do it and what to consider. Build, instead of just tearing down.
