I think the biggest issue with this is that it for once looked pretty arbitrary, and on the other hand, it is something you decided to do despite knowing what the reaction was when the Omicrons changed numbers for letters. It suffices entirely if every faction makes up names for systems. These random name changes do less good than harm, as you see here again. While I see the point you make about Edinburgh and Orkney, I don't see what warrants the change of California Minor into Anaheim. NPCs will still refer to these systems and planets as what they are in case of them having existed in vanilla. People love vanilla content, and you say they treat it as sacred, but you deliberately made the decision anyway.
Something similar with Laptev, less about the name and more about what the system is. A connection from Galileo to Bering. The system itself is boring except for the very nice sun (that has the same error like the red dwarf of Poole and Cologne, by the way, where the texture does not show up except under certain conditions). People having been begging for something like the Deeper Omicrons, You've even teased some kind of development going on with that zipper planet. Instead we got a system that is containing nothing. The connection from Galileo to Bering could just have been two jump holes instead of four. One can't* even go to Laptev in transports/caps. It feels like this was nothing people asked for, except for mimimi my snub needs to be able to cross all of Sirius in less than ten minutes.
Weak patch, in my opinion. And weak justinfications. I bet this will just dismissed with "we can't make everyone happy lol".
