there was a time when DNS wasnt so critical. We would remember a servers IP address, or keep a local DNS table and customize whatever literal URL names for the IP address,now the URL or the link is usually inhuman[mangled; shortened; redirected, incredibly long or complex] and we need DNS.

The DOH is an interesting front. Im thinking about how could someone deny traffic hops to machines with no visible DNS traffic, so if you cant block based on IPs then you can block based on DNS opacity
