> browsers and mobile phones have started using hardcoded DNS resolvers, so the utility of this is limited

Got a source for that? No phone or browser that I'm aware of uses "hardcoded DNS resolvers". They all use the OS DNS servers which the OS gets from DHCP.

By extension, any application or device could rely on DoH instead of OS-provided or network-provider DNS servers. It is controversial, since it both helps individuals combat ISP or government censorship and also helps bad actors do bad things [1].

DoH in Firefox is off by default (at least in every FF I've ever installed). And it's not hardcoded to any specific DNS server, you can use whichever provider you like.
