What's the point though? I can think maybe of reduced latency, but then you usually have the DNS already cached locally. And that takes me to a second point, won't you run into problems delivering content updates, given that clients will most likely cache DNS entries?

Highly distributed global CDN for free. You can use a short TTL, though there are lots of misbehaving DNS servers around cache timeouts. "Fetch with DoH" kinda ruins the party, but browsers can't do UDP or non-HTTP TCP.

In my mind this is a neat proof-of-concept that shows how you can serve content through some absurd method (in this case serving HTML over DNS). It may not have "a point" beyond just being an example of what's possible!

Probably "because it's there".

Yes, that's the case indeed.
