Good question! They would be the perfect players interested in making a better impeller for the D5. I know we like the compactness of the DDC, but a redesigned D5 with better heat dissipation out the motor casing and a much improved pressure oriented impeller design, and we'd have something pretty neat.

They are probably just tayloring efforts on what sells the most, which I suspect the DDCs outsell the D5s several times over.
