I feel like back when D might've been a language worth looking into, it was hampered by the proprietary compilers.
And still today, the first thought that comes to mind when I think D is "that language with proprietary compilers", even though there has apparently been some movement on that front? Not really worth looking into now that we have Go as an excellent GC'd compiled language and Rust as an excellent C++ replacement.
Having two different languages for those purposes seems like a better idea anyway than having one "optionally managed" language. I can't even imagine how that could possibly work in a way that doesn't just fragment the community.
