We've been promised exploration improvements every year since before release. Go back and count the meaningful improvements there have been to exploration, and if you use more than one hand's worth of fingers I know you're fibbing.
I'm the first one to agree that exploration has been the poor cousin in updates thus far - if you've read any of my posts you will know this to be true. But it would be wrong to say that there's been no improvements to exploration at all. The ability to land on more than half of the planetary bodies in the game was a huge step (and caught everyone by surprise to boot, at the time), even if there was initially little to do but admire the scenery. But that has steadily improved, with structures, volcanic sites and biologics to find. The next iteration of that, hopefully, will include improved scanners to help find these (often elusive) sites and surface navigation by a manually entered coordinate-based waypoint. And I fully expect we'll eventually see an expansion of the planet types we can land on, even if initially only basic atmospheres and the like. The recently increased galaxy map plotting range has been a boon for many. Even engineering has increased jump ranges, by directly engineering the FSD and reducing weight of other modules (if desired). Q1 2018 brings the next iteration of planet graphical improvements, so that's not far off and clearly would have been being worked on through the development of 2.4 and probably earlier (so not suddenly being developed in a reactionary way). There's a long way to go, to be sure, and improvements delayed by other content such as Powerplay, CQC, Engineers, even 2.4, but let's see what 2018 brings.
This myth is easily dispelled by a skim of the original project proposal on the Kickstarter site.
The base game was supposed to be complete by early 2014. Not until long past then with still no release and Frontier's sheepish admission that they were going to have to release with "fewer features" did we all realize how incomplete the game really was.
No myth from where I stand. I was a quite early kickstarter backer myself and I was always under the impression it would be an iterative development process. Mind you, I also expected a solo offline mode so there you go....
