> Also OpenBSD is much more of a research operating system then other large successful OS(Linux, Windows, MacOS, FreeBSD, etc). Meaning OpenBSD cares way more about developing features and novel security mitigations then trying to maintain backwards compatibility like other operating systems do.

This is not the feeling I get from OpenBSD at all. They don't act like research. They aren't keen on implementing new features just for the sake of it, or just to try it out. A better description would be that they put correctness, security and maintainability first, and simplicity often comes as a nice side effect. Deprecating old, unused features is just a consequence of striving to decrease complexity by trimming your code base. OpenBSD is one of the few OS where the number of lines of code is not skyrocketing to unmanageable numbers.
