At this point they have to implement the FSD breakdown, because right now it's just an exploit making it this easy. Just like in Beta 2 when you couldn't be interdicted, this will be changing upon full release.
It needs to, because while that sight is cool, it's definitely still unfinished. They're working out the lensing and the physical object, but they're presently using a Schwarzchild black hole, without an accretion field (which isn't accurate, as no non-spinning black holes are theorized to exist). The accretion disk should look like a ring, and the actual black hole is an infinitesimally thin ring stretched out. The brilliant white light is actually where you don't want to fly, with one of these.
But modeling that is super difficult, and doing it was most likely an afterthought, because we've got so long to go before we reach Sag A* once the game is released. I highly doubt that they thought the spoiler was going to get revealed so soon. As such, they're pushed to improve things for when it actually does happen. All things in time, in some ways because of this reveal, they're going to have to step up their game (once they find the time, they've got bugs to work out still)
One thing Zion Ravescene did here was he pushed the game to its complete limit, and probably fed the developers some fantastic data about what happened along the way. It can help them hone their techniques for covering a large amount of systems, or make them switch all their systems to faster servers. So this ultimately will benefit the rest of the community.
