My only gripe with DNS over HTTPS is that it seems to somehow be coupled with making it harder for me to actually force everything to use a particular DNS at the OS level, so apps can do things like circumvent your pihole regardless of how you configure your device's DNS settings.
That is by design though. You want your dns requests to blend in with regular traffic on hostile networks / ISPs. The solution is to not have proprietary spyware devices in your network that don't let you set your own dns.
Now we will have 2 mayor browsers, that might or might not resolve internal domains correctly. And unless you have AD, and ability to push to config clients, you will have to go to each and every computer and set it manually. And hope that updates wont break it further.
I have firefox with DoH enabled and it still works with the companies internal domain names. I'm pretty sure nothing breaks because of the fact that it falls back to regular dns if the lookup fails so internal domains still resolve.
