No it doesn't. You can navigate to long paths, but try doing any file operations (like renaming a file) and you'll see it doesn't work.

Also, the rest of my points are end user impacting. Updates impact everyone and is a very important part of an OS experience. I used to work on a helpdesk for an MSP, and you've no idea the number calls we used to get from users frustrated about updates for various reasons. Hell, we use Windows at work and I still get annoyed as a user.
