We believe that this is one of the main reasons why > DNS-over-TLS failed to gain significant traction. The last sentence really surprises me. I'm actually not convinced that protocol details like this can *directly* affect large-scale adoption, so to find this it might be more interesting to ask the most popular DNS clients why they chose the way they did. AFAIK it's not too common to support both (equally). I would think the main reasons will be far from the suggested one, but I didn't try to find out... except that for web browsers it's probably natural to prefer DoH, as they're all built around http(s). --Vladimir
