There are no easy solutions that will please everyone that does not need a complete re-write of the FSS or a complete bypass of it.
FDev are not going to remove the FSS
Why not? There is precedent of it happening. The FSS should not hold exploration back if Frontier would implement better mechanics for it. Hopefully, the New Era or after of Elite will also include a rethink of exploration from the ground up, because by today, Frontier are doing many things backwards with it.
For example, you can interact with some stuff other than just using your scanner on them, but doing so pays peanuts and is mostly pointless. You get the most rewards from the bodies you can least interact with. You fiddle with a minigame to identify bodies, half of which are just pretty (but very pretty!) marbles gameplay-wise, but you do a chore and then fly to the exact location of the possibly more interactive stuff. Which, again, isn't very rewarding, unless you are looking for specific materials. (Which is unrelated to exploration.) They tried to add gameplay and remove flight to lessen downtime, but ended up making the surface POI scan times far too long and clunky.
There's also that Elite is arguably at its best with a HOTAS and a VR headset, yet the FSS is actually the worst with these (and the best with a 2D screen and gamepad or KB/M).
A lot of the mechanics around exploration come from the fact that all the game had at the start was the generated galaxy, very little in the way of hand-crafted content, not enough time to implement deeper mechanics around exploration, and of course no landable planets at all. We'll see if Frontier will continue with this legacy around and after the next expansion, and just try to put band-aids on it, or if they'll take the time to rethink the fundamentals of exploration.
And I haven't even mentioned the most common complaint with it: the monotony of interstellar travel, or in short, JJJJJJJJ.
Honestly, what irks me about the FSS/ADS debates is that Frontier could and should do better than either of those.
