I wish I had your problems. :D . Problems that are really only a mild inconvenience, and can be solved with a single line in hosts file.

My biggest and possibly only problem preventing me from going IPV6-only is that Github doesn't support it, and there's just too much darn software I need to needs Github. (Yes, I know NAT64 exist - it's just extra complexity for something that is not even my problem in the first place).
