I mean, as someone who identifies mainly as an explorer, I feel your pain. The planetary exploration as it stands is pretty brutal. However, it's not like they've been working on atmospheric planets for five years. They only came out with landable planets at all not long ago. It's super depressing to find a system with all kinds of fascinating worlds -- earth-likes, water worlds, gas giants with various kinds of life, etc. -- and only have the 37 ice bodies be landable and all more or less identical (and brutally mountainous and impossible to drive on such that visiting a single geological single could waste two hours of your time just harvesting 2-3 piceous cobble) -- but it makes sense as the first step in a gradual release of a wider range of landable planets.
Now, if you ask why the DSS mapping function is still so buggy, THEN I can get worked up.
