Even if technically correct - totally irrelevant when it comes to game mechanics and gameplay. Way more relevant might be considerations about how to gain time to render the system bodies. In already explored systems this can be fetched from the local server, at least partially. Unexplored systems still have to be procedurally generated, even when the positions (again: technically) are already known.
All what matters to players is if we are meant to see the positions, not what's actually known on code level.
That's a bit of tinfoiling, but I can see that time for procedural rendering will be getting more and more relevant in the future IF they plan to enhance on planetary types and surfaces, including atmospheres.
The ADS would lead to situations where you'd have to wait several minutes until the honk is solved. All the hidden calculations can barely be hidden by the primitive ADS mechanics. I'm pretty sure the ADS in a future incarnation of ED would be a very frustrating experience, even to those who called for it and that the devs just had to realize that the ADS has no future.
Yeah, the rendering situation's already problematic which can be seen when using the FSS for landable worlds with vulcanism and the long scan times to detect geological sites.
It's almost certainly to be highly exacerbated for more complicated bodies if/when atmos landings comes.
Not sure that's an argument against an ADS style mechanism though - do a black box only, or minimum render type scan, and the more detailed render time is concealed by the time taken flying to the bodies to do the scan. It would largely mean no detection of POIs from a distance though.
(And please please, don't get carried away by the above, anyone, it's just speculation and I wouldn't want anyone to get their hopes up for a potential reason/avenue for a return to the ADS only to see them dashed. Exactly the same approach of limiting the rendering should also work for the FSS so this is just a case of something not being a case against the ADS type approach, not a case for it.)
