I am sorry but I am not willing to waste so much time. Not only that but it's impossible for portage to know this before hand unless some dev puts the information in the ebuild. And the infra to check that does not exist. This is all right correct and proper. The only way to know an update breaks something is to build and test it. That's how Ubuntu does it: the dev builds it, installs it, finds it breaks stuff. So it gets committed to a repo with a warning that *the*dev*already*knows*about* The Gentoo dev DOES NOT know about it, and cannot either. These breakages are usually dependant on the environment they are used in and only the user knows that.
