It is trivial for any "large app" writer to invent a proprietary way to do DNS resolution - please please, let's keep the DoH (protocol) versus "apps doing their own resolution" separate.


A standardized DoH enables alternative interoperable service infrastructure to be formed and not be easily blocked by access providers.  That’s different from all other models, and it has ramifications. The point is that our providing the path of interoperability means, as Paul Vixie points out, that we owe it to ourselves and to the community to understand those ramifications.

We have been here before.  When the IAB allocated 10/8, they were providing an interoperable method for private networks in direct response to people picking networks out of a hat.  It too had substantial ramifications.[1]*

It is absolutely possible for the existing infrastructure to adopt DoH, and I suspect that will happen.  But that is not the driving use case today.  An alternate DNS infrastructure is the driving use case, and we should be mindful of that.
