It even blocks self-hosted analytics scripts from the same domain. By default.
I don't see how that is a good thing. It just makes the lives of people who run websites harder. When I visit a website, I have some sympathy towards the person who runs it.
Disabling scripts which talk to self-hosted analytics software makes it hard to figure out how users use a website. Especially when the site is using a CDN. So people enable tracking on the CDN level. Which means now CloudFlare, Amazon etc store that data again. Lose-lose for everybody.
