From Aquinas' Summa Theologiae. The argument this article presents does seem very similar. Weirdly, the article itself is very dismissive of religion, while making a similar argument to the one Aquinas made 750 years ago.
If this mode of operation was an explicit choice, this would give me the option to have a fallback SPF record for legacy mail systems, but most up-to-date servers will use the more secure and (for my use case) operationally simpler verification.
And on the receiving side, the policy is similarly simple: if I receive any unsigned or unaligned email, I will reject it.
Edit: to clarify, I want there to be an option where I specify my DMARC policy to explicitly tell well-configured receiving servers "ignore whatever I have configured as my SPF record, only look at the signatures". There will no doubt be a long tail of mail servers where I will still need an SPF record for them to accept my mail.
Edit2: Another feature that I feel is lacking is ability to give dkim selectors a scope - e.g. this key is only valid for these particular From addresses.
My own service images already have a script that runs daily that pulls latest git updates and builds fresh images.
Went with openSUSE MicroOS myself, it updates and reboots almost daily so I can be pretty confident my server is healthy and it's atomic so if something does break and I don't feel like dealing with it, I can just click rollback button from cockpit and deal with it whenever I have time.
Could Cloudflare be more proactive or add more friction to their signups? Yes, probably, but the reasons they have outlined for not playing internet police make sense to me.
I don't think it should be a requirement to provide your credit card, phone number and a copy of your ID in order to host content on the internet...
Another thing that will always trip up new IPv6 network engineers is solicited-node multicast. You know the theory, computers talk to ff02::1 for neighbor discovery and then you hop onto a real network and see none of that actually happening.
And probably the most complicated thing for network engineers - how to set up firewall rules if machines are constantly changing their addresses.
For developers and security people - just parsing and validating v6 addresses is a whole bunch more work, but at least for this, the tools are available to help you now.

The manipulations I will need to do to fit into the 63 char limit will be atrocious.
Want to set up a new domain for whatever purposes (conference, new product, etc)? Be prepared to spend the first half a year fighting the various blacklists before people can actually reliably connect.
Would make so much sense if you could just have a .well-known/other-domains.txt (or something something DNS) with a list of domain names that should be considered just as trustworthy as your main domain.
It's not even about .online or other weird TLDs, it's just that the domain is new and therefore "not trustworthy". Even worse if you need to use your existing branding on the new domain - instantly flagged as a phishing site everywhere.
As an aside, I am super annoyed at Cloudflare for calling their proxy records "CNAME" in their UI. Those are nothing like CNAMEs and have caused endless confusion.
I decided to give desktop Linux another shot and I'm glad I did. I was prepared for a lot of jankiness but figured I have enough experience to fix whatever needs fixing. Surprisingly, this has not been the case at all, the PC has been not only as stable as Windows or Mac but also performs better and is much more comfortable and intuitive to use. I never really want to "work on" my personal computer, I want it to just be there for me reliably. I've always had a soft spot for free software, but I just couldn't justify the effort until now.
So I guess this is my love letter to all the devs that have made the modern Linux desktop possible. Even compared to just a few years ago, the difference is immense. Keep up the good work.
