Saying this as someone doing Web related development since 1998, glory days of Perl and CGIs.

It's kind of funny in hindsight, but at least we didn't have to modify every project just to update such a minor thing which was working already anyway.
In this regard the thing that absolutely sucks is the migration tool. Your best course of action is to update the versions manually in package.json, read the documentation on breaking changes and act accordingly.
In my view Angular was always insane, but it's becoming saner with each subsequent version. We now have typed forms (that took a while), standalone components and, most importantly, signals, which do most of the stuff RxJS is doing, but without the junior-killing hidden state and memory leaks.
