In business settings, I've seen plenty of pull requests "go stale". Usually, they come about from a) the person not updating their code based on reviews, b) the reviewers not reviewing in a timely manner, or c) the change is no longer necessary / a priority.

Usually, it is some combination of a and b. All cases are an indication of a deeper problem. None can be fixed by calling your "pull request" a "managed push" nor by giving people unrestricted access to pushing code. It's typically either a problem with communication or priorities/expectations.
