@ Baroness Galaxy: Fully implementing the GMP wasn't a realistic option, due to names like Wagar's Reach, Anthor Patch, and so on. The new names have some questionable ones, but the GMP names have just as many. As for including the GMP map as an overlay in the game: it would be a nice sentiment to them, but I can see why Frontier wouldn't want to add an overlay to the galaxy map that would have no functional use for any game mechanic.
Mind you, people can and probably will still use some of the GMP names, especially when they want to relate some place that doesn't entirely correspond to a galactic region. Although... I'm not sure there'll be any. The region names don't always sync up entirely with the geography of the galaxy, that's true, but for the most part, there has been little practical need to use names for many places. After all, they rarely saw any traffic, and weren't special enough to merit a specific mention. (I'm not even sure why FD went with Hawking's Gap originally, when the abandoned settlements weren't even in the gap proper.)
If as you said "everyone is respected in the end", then you'd have to include all the different communities in naming regions, not just those on the GMP team and the English (mostly PC) official forums. As it stands, the GMP team does not stand for the exploration community - no single subcommunity does - so if Frontier were to use their names exclusively, it would have meant excluding the majority.
At the end of it all though, we've long known that unfortunately, players rarely ever get to name anything, Frontier reserves the right to do that for themselves.
Oh, and the Norma Arm isn't a GMP name, it's a real one. Qohen's map that you linked erroneously attributes some names to the GMP, like the Formidine Rift and some real arm names. On the other hand, it doesn't mark Hawking's Gap as a GMP team name.
Also, no offense, but what the surface prospectors produced wasn't fan lore, but data. It was a good thing that surface materials were made accessible to all, as opposed to having no idea what you might get until you shot a lot of rocks. Shouldn't have been thus in the first place, but well, that was hardly the only game design error that FD made.
