It's an entirely hypothetical discussion, because FD aren't going to be spontaneously creating any entirely new star systems inside the Bubble. That would cause all sorts of problems with Powerplay and the BGS.
Example: when the astronomers announced the discovery of "earth-like planets" in the TRAPPIST-1 system a year ago, people clamoured for that system and those planets to be added to the game. Some people did the math and discovered there was a procedurally-generated Y-class brown dwarf system in roughly the same place that TRAPPIST-1 would be, so FD manually edited that system, changing the star to an M-class and editing the planets to match those found in the actual TRAPPIST-1 system. Which even included an actual Earth-like world (21st century exoplanetary astronomers have an entirely different definition of "Earth-like" to the ED definition).
But they didn't make TRAPPIST-1 inhabited. That would have thrown out the BGS for every star system within 15 LYs of TRAPPIST-1, as well as altering the dynamic of Powerplay in the region (more people = making the area more profitable). Yes, it does mean that they need to explain why an inhabitable planet only a few dozen LYs away from Earth and well within the Bubble, that we've known about the existence of since before the invention of interstellar flight 1200 years ago, has never been colonized. But writing some handwavium lore (I prefer the Galactic Park hypothesis) is easier than making the BGS and Powerplay players mad.
Now, that being said, there are an awful lot of already-colonized planets within the bubble that have never been given a "proper name". The only planets with actual names are the "FE2/FFE legacy map" names, and the Kickstarter names. I find it unrealistic that a planet that's home to billions of people and has presumably been colonized for over a thousand years has never been given a name that's better than [name or catalogue number of star] [orbital position number]. Humans aren't like that. We like to give names to things, and the places where we live are pretty high up on the priority list of things-we-need-to-give-names-to. And I'd guess there are tens of thousands of inhabited-yet-unnamed planets in ED.
A reasonable compromise, though a lot of work for FD so it still probably wouldn't be implemented: every player is given the option to submit one name. FD sorts through them and sifts out the obvious troll-names. The rest get randomly allocated to the un-named planets.
