It could still be on the cards, we don't know
But it's not a priority.
We currently have the galmap, which is 3D, you 'fly' around it, it's distances are scaled accurately, and is capable of showing the most basic info on an unvisited system (main star class, and in realistic view, whether there are multiple stars).
We have a zoom function that allows you to zoom way out far beyond what is essential, because it's cool to be able to look at the whole galaxy sometimes, even though we would never need to be able to navigate to a star so far away, and to select a star that far away we have to zoom way back in anyway.
In the current system view for landable planets if you keep zooming in it switches to single body view, which again is 3D. The close end of the zoom here is a little more restrictive, it goes as close as is required & no more, it's functional but although it would be pretty cool to fly around the surface in the map, you can only get so close, and only view the body head on.
So what stands out as incongruous is that the system view, the middle bit, is a 2D hierarchical view rather than a realistically scaled 3D representation. But it's a practical way to organise all the known info about a system, we don't
need more than it provides.
So what would be cool would be if we could, from the galmap, select a (visited) system, and continue to zoom in until the view we have shows orbits and scaled distances, then continue to zoom in again into single body view as we have now. The galmap can show trade routes between systems, the orrery view could similarly show those trade routes within the system from the entry point to a body or station, or possibly between bodies.
But is the rule of cool enough on it's own to justify adding to an already complete set of views (as far as practical use is concerned)? Maybe. I don't think so, but it's not up to me.
