What was the niche C++ aimed for a couple decades back, C with 
objects?  D is aiming for the same "niche" as C and C++, a 
general-purpose, native-compiled language that allows you to 
extract almost-maximal performance while still being relatively 
easy to use, at least compared to the alternatives.

Perhaps focusing on a smaller niche first would allow D to gain a 
larger following quicker, but that might box it in from becoming 
more general-purpose later, as early decisions optimize for that 
niche and might be tough to undo.  Go certainly seems stuck in a 
niche now, though I'm not sure how much of that is because they 
just don't want to add more general-purpose features like 
generics, ie they're happy in their niche.

C and C++ are very general-purpose, but they can still be 
considered as a "niche" of performance languages.  What's wrong 
with D aiming for that "niche?"
