The station was used for spare parts in one episode if I remember right, and in the books its fusion core was used for DS9 as well. In the books, the entire station was towed at warp by a small armada to the Bajor system for use for other spare parts over time as well.Of course, this was all rendered moot with the destruction of the original DS9 and the construction of a new one made with Federation tech.
Thanks for the perspective from the novels. I have yet to get the time to read most of the reboot. So, I’ll be glad to see it used when I do. :-)
