The problem is that, in DoH's "obfuscated traffic mode" (is that better than "dissident mode"?), increased transport privacy for the individual (not necessarily increased privacy, but that's a different story) is obtained at the expense of network security. Other tradeoff points are possible, giving the user almost the same amount of privacy but also more security, so while I find it justified to push the tradeoff to the extreme side of privacy when someone's life and freedom could be at risk, I would prefer a more balanced tradeoff point (the one in which DoH traffic is clearly identifiable and can be blocked by the network if necessary) in other contexts, at least as the default.

More generally, beware that if you build an Internet that is designed to work as if everyone on the planet were a dissident in an authoritarian country, it is not unlikely that you will then get an Internet regulatory and access environment that looks like the one of authoritarian countries, even in democratic ones.
