It's honest communication, something that is becoming increasingly rare in this world of language policing. It's good to be nice to other people, but History as shown us time and again that freedom of speech is a very precious and important thing.

> Not having good comments and test cases for intended behavior is a bad practice.

This might be true, but nobody really knows for sure. There isn't a single development methodology that has been shown by rigorous experiments to be any better than anything else. In this case you have experienced developers doing what they think is best. Emacs is a very old and widely used project. There are very few software projects at that level of sustained impact (which is what actually matters in the end). Some humility might be wise.
