I think it's fair game to discuss Rust in this context since there's a major effort underway to support writing in-kernel drivers in Rust. Unless you think the kernel will be a bazaar of languages, then it's useful to think about which language is the most likely to "win".

I think it would be of value, to a degree, if the kernel supported multiple languages. As some languages are better suited for some tasks.

This implies comparing them, so I understand your point now.

There are other OSes out there where D could eventually make a mark.

Naturally the whole issue is that there is no big movement regarding writing OSes in D for that to matter anyway.

Better luck using TinyGo, Java, .NET or Oberon in bare metal workloads (where runtime plays the OS role), as there are a couple of products for them, than D.
