Sarcasm aside, I've worked with codebases like that- thousand-line java methods and classes and the like. The problem is that there's nothing that really forces modularity on a codebase. There isn't even any consensus, objective way to modularise code. Otherwise, a machine could do it and we wouldn't have this kind of problem. But, a machine cannot, and so we do.

First of all, I don't think people report this type of stuff because they don't know how to report it, and secondly think it doesn't need to support this use case anyway since space is a latecomer to naming and path game.
