> No dependency on a registrar sounds nice.

Actually the main benefit is no dependency on DNS (booth direct and root).

IP is a simple primitive, i.e. "is it routable or not ?".

The popular HTTP validation method has the same drawback whether using DNS or IP certificates? Namely, if you can compromise routes to hijack traffic, you can also hijack the validation requests. Right?

		Yes, there have been cases where this has happened (https://notes.valdikss.org.ru/jabber.ru-mitm/), but it's really now into the realm of 1) How to secure routing information: some says RPKI, some argues that's not enough and are experimenting with something like SCION (https://docs.scion.org/en/latest/) 2) Principal-Agent problem: jabber.ru's hijack relied on (presumably) Hetzner being forced to do it by German law agents based on the powers provided under the German Telecommunications Act (TKG)
