This seems to be a static vs dynamic setup. Either you use dynamic and you will happily accept what you get from DHCP and possibly upgrade to (HTTP|TL)S or you have set your resolvers statically and you are already ignoring the nameservers provided by the DHCP server. If you do not accept the servers provided by DHCP, there is no reason you would accept extra attributes for those same snameservers.

Yes, those are my thoughts precisely.

I don't see a risk model where a user configures DOH or DOT servers explicitly, but does not disable DHCP configuration for DNS. Am I missing something?
