While I can understand your feelings, I simply can't see it that way. From my point of view:
1) From a pure credits point of view, the FSS "mini-game" wins by a landslide. If all you care about is your credits/hour rate, using something similar to the old ADS simply adds a few steps to the process. There's no
real advantage to restoring an optional ADS analog back into the game.
2) The system map only reveals orbital heirarchies and icons of planetary types. The FSS is capable of doing both without needing to play the "mini-game", and you can use it to identify phenomenon that the orbital map
doesn't reveal such as rare planetary alignments (like eclipses) and close orbiting binaries. This, IMO, makes finding scenic locations for screenshots, or simply gathering materials, easier than an optional ADS analog. Doubly so if Frontier goes with the "black body" approach.
3) If some people are correct, and the "new era" will mostly be about planetary POIs, gaining proficiency in the FSS will give you leg up on those who might've relied on an optional ADS analog for their exploration.
4) If I'm correct about there being even
more information encoded in the FSS than what I've already discovered, then gaining proficiency in the FSS will
also give you a leg up over those who simply spam the "mini-game" for credits.
