Somebody who is developing Emacs will have the git repository.

In what sense does Emacs differ from other GNU packages, like Coreutils?

Coreutils has a series of tests that are similarly "useless" for anybody who isn't developing Coreutils. However, builders of Coreutils can run 'make check' to run these tests. If tests fail, builders can decide themselves whether to install the build, or to stick with an older version. And they can report problems to developers, often problems that the developers themselves couldn't easily find. The developers and builders can then collaborate to fix the problem. Yes, the process can be a bit awkward, but it beats leaving the bugs unfixed. And no part of this process requires builders to understand the code well enough to fix it.

Why shouldn't Emacs do that too?
