Which is why I don't think users who *might* end up in a captive portal should 
have DoH-without-fallback enabled unless they know perfectly well what they're 
doing and can get themselves out of it.

A DoH-without-fallback config has several other quirks as well with local host 
names etc that I doubt a lot of users will experience that without having 
asked for it themselves.
