You wrote: "The choice of resolvers was previously made by the network on which the user was connected. Recently, the Internet Engineering Steering Group approved the standardization of a mechanism so that the choice can be made by a web browser. " This isn't correct. Web browsers have *always* been able to choose their own resolver because DNS is just UDP packets, which the browser is quite capable of sending (e.g., QUIC, WebRTC). Historically, browsers have chosen to use the system resolver which customarily gets its choice of resolver from the network, however, Chrome, at least, for some time has done DNS resolution itself, albeit using the same resolver as the system resolver used. However, they could easily have chosen to use 8.8.8.8 (or some other resolver) instead. The point here is that DoH is orthogonal to the question of which resolver you use. -Ekr
