Why so? Couldn't we have a nice overview of what kind of signed modules are valid in their integrity and authenticity based on cryptography? (Also I wanted to point out that LD_PRELOAD was specifically mentioned in my comment, but it doesn't really matter, it's the lack of integrity checks across the /usr folders that are part of the problem. Glibc, $PATH, sideloaded .so files, kernel hooks...it's such a vast problem space of insecure development practices that by now we need a better OS architecture because all (old) tools down the stack rely on 100% trustable programs being installed, which after the invention of the internet is not a reality anymore.)
