Sure, I've done a few bare metal applications with D in the past (most recently, my little webassembly toys use the same technique, though webassembly isn't exactly the same on hardware level obviously, it still acts as a bare metal target as far as plain code goes). In my "D Cookbook" I had two examples, one for x86 and one for arm, showing it.

It has gotten easier than it was back then, but you still have to do a lot yourself though, but that's true for any kind of OS dev. Not something you'd want to take on without already being pretty familiar with D, and knowledge its druntime internals help a lot if you want to take it to the next level using more language features.

Very interesting. I've just learned that the lead developer is Ikey Doherty, a name I don't recognize. Does he appear on D forums? (To make it more interesting to me, there is some Turkish connection as well, which I had not heard of either.)

And many other parts but not the kernel, right? As I understand it, the kernel is being developed by a completely different group:
