I used to (I still own it actually) operate one as a pet project for a smuggler hub.
Turns out smuggling remained extremely unpopular over the last 4 years, so I abandoned it. Joke being it is actually invincible.
I helped building up the DHC PoB for example, as Major stated, it's sole purpose was ore storage. It did well as such but that is it. Either they are ore storages or pet projects tbh.
