It is an old news now.
They decided to use Go, because it was closer to the language of 
their initial implementation (TypeScript).

D is expensive for production in most of the cases.
In wider terms I would say it is not production ready.
{
Yes, I know there are companies that are using it in production.
Even several big ones like Weka and Symmetry.

No, it's not enough.
}

So I don't think they were considering D at all. Most probably 
they had some short-list of the language that their team knows 
and that are suitable for the task.

Something like C#, Rust, Go, C++

And not sure if ecosystem was a significant weight in the 
decision.
