As for why no other has adopted it, it really only makes sense for bytecode based stacks, and there is no competition to CLR for low-level languages.
Not a good sign for D needing to adopt managed pointers.
There is no demand for having a GC in c++ either. The GC support in std is being removed in C++23, and very few projects use the boehm collector (which is very close to the D one).
Cabon will also not have a GC (maybe ref count optimizations). Likewise Rust.
So there is no indication that there is a significant demand for GC among system level programmers/corporations that depend on system level code bases. Not even as an option.
And even the Microsoft example is basically about interop, not system level programming.
But you are right that it is attractive for anything that happens at compile time. However, if you want GC to be attractive at runtime then you need a new strategy at the language design level where threads dont have a negative impact on each other. Even then it will be an uphill battle as will need to create a demand for it (you would need to change existing practice).
(Swift and Go are usually not considered system level.)
