In other words, they haven't figured out how it could be used in combat. Since it's not combat related, it's not important.
In all honesty, that probably has a lot to do with why Frontier doesn't feel it's important. Sad as it is, they so often focus on combat content that it would be very easy to believe:
- Tech Brokers, mostly combat stuff
- Engineers, 90% combat stuff
- SLF's: combat content
- Last two ships added to the game: combat ships, with the upcoming Krait likely as well
- Thargoid content: combat stuff
- New 3.0 Guardian content: blowing up sentinels for mats is a large part of it
- New C&P system: entirely combat focused
- New Megaship content: combat stuff
Now if we could only find a way to make the Orrery Map combat related we'd finally get our fancy system map!!!! Same with surface waypoints and bookmarks, most likely. [sad]
