Then don’t get me started about how the www subdomain itself no longer makes sense. I get that the system was designed long before HTTP and the WWW took over the internet as basically the default, but if we had known that in advance it would’ve made sense to not try to push www in front of all website domains throughout the 90"s and early 2000’s.
I have never understood why you can delegate a subdomain but not the root domain, I doubt it was a technical issue because they added support for it recently via SVCB
records (But maybe technical concerns were actually fixed in the decades since)
What you see in stuff like Google Maps or OpenStreetMap isn’t plain Mercator, it’s a variant called “Web Mercator”
And the US DoD doesn’t like it because it introduces even more deviations than plain Mercator.
