Building such a library is a lot of work, as in, if you're only 
working in your free time, a multi year long task. Sklearn, for 
example, took like, four years before it was in a state where 
people wanted to use it, and that's built off of many C and C++ 
projects.

Sure, there are a lot of C libraries that D could provide 
wrappers for, but that's not what you're talking about. A true D 
library that takes advantage of the compile time features would 
have to include thousands of new lines of D code. Plus, in order 
to be taken seriously, any new code must be as performant as 
possible, so the writer must be skilled in writing low level code 
for a lot of platforms, which takes a lot of time.
