I dont know what it would be useful for in the wider context of 
software development I will just explain my use case.
I work in a fast paced industry where there are new things every 
single week, its art based and I need to write scripts to 
generate things very quickly they are one off and never used 
again, D is better for this than most other languages the only 
languages I found that were better for scripting were languages 
like Common lisp, scheme, and julia, languages like that are fast 
to write and fast to run. (obviously not including libraries 
otherwise python would be the best, as I prefer to write the code 
and not use libraries)

my second use case is long term production code for generating 
things for work, it needs to work for a long time, and be 
extended with scripts in emergencies, the production code also 
needs to be graphical at least at some point.

D is the only language I have found that allows me to do both the 
scripting workflow and production workflow in one language, every 
single other language I have tried has some major barrier, I 
checked dozens of programming languages, most have obvious issues 
where I didnt need to write any code to see it wasnt useful, like 
I refuse to use an interpreted language, or were too new for me 
to trust as I am going to be using the language for many years.

I think one reason people dont use D is because its good at 
everything, its good at scripting and production code, but for 
scripting its not as good as other languages, and for production 
code its not as good as other languages, most people are extreme 
in either of those directions, few people want balance, thus why 
they use Rust or Go for production, and python for scripting.

realistically I think its easy to prove its a dumb approach as 
many companies have spent millions of dollars re writing there 
python back-ends in faster languages, if they would have used D 
it literally would have saved millions of dollars, it should be 
an easy sell, D will save you money because worse case scenario 
you can always make your code faster, if you cant its a problems 
with your skills, not the language.

so to answer your questions D's best niche at least in my opinion 
is any situation where its a good idea to write a script first 
and write production code later, which is virtually everything.
