It is the optimal way to tag stuff & earn cash though. Since 3.3 I have more money than I know what to do with for the first time since I bought the game in January 2015 because pretty well every system I enter I scan everything to get a completed map, but map no more than I scanned pre-3.3.It depends upon what you mean by "full capabilities." Quite frankly, I consider spamming the "minigame" to be not using the FSS's full capabilities myself.
The net effect for me is that completion scanning the system has become the new honk scoop & jump (ie added delay before I get to see whether the system contains anything interesting to me), then because mapping has become the new scanning I 'have' to fly much closer to the body, come to almost a complete stop & fire the probes, compared to the straightforward fly-by I would do before which would allow me to get a feeling of the scale of the system.
I like the benefits of being able to optionally scan at a distance, and mapping is almost entirely optional so I don't have a problem with that at all, but all it's done for me is slow me down & provide a compensating benefit I I don't consider important.
