The challenges around changing hosting providers are the same for websites, aren't they? It seems to me they are well understood these days. I don't hear many people having a pain point around it anymore. A short TTL usually is enough to avoid a lot of DNS caching issues.

And wouldn't changing the name server have the same effect on the DNS solution? "Every time you change your name server provider ...". Which for many users is the same as their hosting provider.

Do I assume correctly, that you don't link to the HTTP fallback documentation because you don't want people to use it?
