D is really unique in the sense that it's open enough for people not to feel that they have to role their own. D also has enough features to satisfy many different users, although - and this is often forgotten - you don't _have_ to use them all. People like Go and Rust, because it tells them exactly what to do. D doesn't, they have to think for themselves, and a lot of people hate that, which is sad, because having loads of things to choose from makes you think more about your code and software design in general and it makes you a better programmer/coder/architect.
Thinking like that is fine when you work on your own, but when you're in a large team and working on a large code base the prospect of trying to grok a dozen different coding approaches using different feature sets of some uber language is entirely unappealing and best avoided.
