Yes, however the difference here is that Chrome is looking at the OS resolver itself first; not just disregarding it, or looking for a magic domain. Chrome is being opt-in, Firefox is being opt-out.

Chrome DoH use cases:

For the average home user, fine; they're either using what the ISP DNS is, or the public ones (1.1.1.1, 8.8.8.8 ....) If those are on the 'accepts DoH from us', then it'll use DoH to the appropriate destination.

For the corporate environment, their internal DNS might not support DoH, and as such, Chrome will not even try to use DoH.

The key is that it is respecting the OS DNS settings, not the ability to not resolve a magic domain. If I opt to setup DoH internally, the understanding is that I know what I'm getting into.
