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).
