I suggest that you read "The Garbage Collection Handbook" which explains this in deep detail. I'm currently reading it, and I might write an article about the entire D GC issue once I'm done with it.

I think the short version is that D being able to directly call C code is a huge problem here.  Incremental GCs all rely on the GC being notified when pointers are changed.  We might be able to manage it for SafeD, but then SafeD would basically be its own language.
