I mean, I get how this is how I might not think to keep it up to date–but I would never submit a pull request or approve one without checking this kind of thing. The balance of requiring effort from the writers, maintainers, and readers of code is always in flux, it’s true. But if you’re building something big enough that people working on it can forget how a part works, you need comments, and you need them to be good, and, moreover, the kind of people who don’t care about keeping comments up to date are not going to be keeping method names / abstractions up to date either.
