That's true, but you can write C code in D as well, so switching to D won't make people write idiomatic code either. If they won't learn how to use one correctly then they won't care enough to use another correctly.

And if your company won't let you upgrade compilers, then it certainly won't let you switch languages altogether.

With a Pascal like type safety. You need to be explicitly mark your code as @system to be allowed to do C like tricks.

This alone is a very big advantage.
