This list sees a lot more updates than you'd probably think: https://github.com/publicsuffix/list/commits/main/

I was looking at this in terms of trying to keep an app up-to-date, and there was a lot more churn than I expected. If you have a security reason to be reading this, you may need to put some effort into maintaining this... at least, technically. I doubt there's hardly an app out there "properly" keeping up with this and the world seems to largely hold together even so.

TIL! Guess I have to do a `go get -u golang.org/x/net/publicsuffix` now.
