If your site depends on a DNS extension that's only 3.5 years old (and designed to be optional), I think it's fair to say your site is just offline for some users due to a config mistake.
You're free to set up your servers however you like, but there's wisdom in Postel's law.
For the lazy like me: robustness principle, aka Postel's law

Thank you for the reference. I learned something today!
> A flaw can become entrenched as a de facto standard. Any implementation of the protocol is required to replicate the aberrant behavior, or it is not interoperable. This is both a consequence of applying Postel's advice, and a product of a natural reluctance to avoid fatal error conditions.

Archive.is is not making an accidental mistake. Archive.is is behaving very intentionally. They've said so on Twitter. And I believe profmonocle agrees with me on that point.
Just to give you more insight. Google knows which IP address I am using Gmail from. If I use 8.8.8.8 they know what other content I am looking for which websites I visit and tie that to my account. If I use something like Cloudflare who do not expose my IP (or range) then I achieved more privacy. I could use my local DNS server (like I do at home) but I travel a lot.
In this case "misconfiguration" is actually for privacy and archive.is could live with that just like other sites but they intentionally screw with Cloudflare (aka the users who has 1.1.1.1 as the resolver).
This statement is based upon a terrible misunderstand of Postel's
robustness principle. I knew Jon Postel. He was quite unhappy with
how his robustness principle was abused to cover up non-compliant
behavior, and to criticize compliant software.
Jon's principle could perhaps be more accurately stated as "in general,
only a subset of a protocol is actually used in real life. So, you should
be conservative and only generate that subset. However, you should also
be liberal and accept everything that the protocol permits, even if it
appears that nobody will ever use it."
Further discussion on the topic:
The exact same command fails when sent from Cloudflare's datacenters, but succeeds when sent from DigitalOcean:
