I think apps on mobile will start using DoH instead of respecting local network settings. The next logical step would be to sniff SNI on a proxy, but this will remove that ability too. Unless Google/Apple ban apps from ignoring system DNS settings, I think it's reasonable to assume most apps will start querying DoH servers directly.
