I use Mono-D and VisualD extensively, and in lieu of those, I fallback
to makefiles.
Those certainly did make their own equivalent build systems matching
the IDE's existing styles.
Those IDE's integrate D nicely with the C/C++ experiences.

I have no idea how Eclipse operates internally... and I shouldn't have
to. Isn't that the point of an IDE?
All I can say is that CDT works, and I don't know how. If DDT doesn't
automatically work with it out of the box, then the IDE experience is
kinda pointless (to me at least).
If I have to fiddle with a build system by hand, then that undermines
the whole point of the IDE as far as I'm concerned.

C/C++ and D are related, and they must interoperate. It's the top of
the D roadmap.
If I'm an IDE user, I think that's more-or-less an admission that I
don't understand build environments, and I don't want to.
So from that perspective, I think it would be valuable work to make
sure DDT and CDT understand eachother.

There may very well be, but it would seem to be more work than not,
and added complexity and for the cost of additional work doesn't make
for a good sales pitch :)
As far as I can tell, dub is good for self-contained D apps, and
that's about it. Beyond that, there are much simpler solutions, and
that includes IDE support.
