If all you do is ADS then exploration would be boring but it is only the first step in the process... this step has wider implications outside of pure exploration so should be left as is. Those heavily focused on messing with the DS mechanics seem to be ignoring the wider implications of such a change.
The surface scans, which are exploration centric, do currently depend on visibility and range - this is the area which should be built on and refined.
The ADS isn't a "step" though. It's just a big toy button to allow perfunctory player participation points. If it passively honked itself, the gameplay contribution would be the same.
But here's a crazy idea: why don't we wait until Frontier showcases the mechanic before we complain about it? I have a feeling that the eye candy alone will be worth the wait. But don't worry too much if you don't immediately love everything about it. I mean if they can change it once, then they can change it twice, and something tells me that Frontier enjoys having all of it's player base as happy as possible.
