The security barriers for getting keyboard events in macOS are not as simple as “root has access to everything”, and for various reasons can’t and shouldn’t be that simple. So ignoring that part, Apple could make this into a one-click solution, but the number of legit apps that need to do this are so small that it’s very unlikely they will dedicate engineering time to it.

This is obviously where open source is superior. Apple probably can’t justify cleaning this up in macOS, but you can just go in and make it easier on on Linux if you have the knowledge and time.
