There are a lot of mind-bogglingy obvious features Windows lacks. For example, there should be a simple menu that controls what entries show up on the right click menu and in what order.

A user could accidentally do it and end up with a 'broken' menu they don't know how to fix, and Windows being 'broken' in that way is Windows' fault from the perspective of such a user.
This sort of thing can and does cause a support burden, which is an expensive tradeoff. So rather than it being a built in capability, a user would need to manipulate the registry or use a third-party program to do it for them.
At least, that's the reasoning that would've come up at MS when adding such a feature was suggested internally (and it certainly has been)
