It's not a reliable sign of a good developer at all, although you'd be hard-pressed to realize that if you're hip deep in the culture.

My experience from interviewing other devs begs to differ. But why have a discussion when you can just ad homiem people?

In my experience this shows that people actually care about the tech they work with. Which is a good sign.

Caring about tooling doesn't mean you can necessarily use them well, especially when rhetoric becomes codified.
