Why are orbital EVA reports (instead of crew reports) biome specific?

One thing which puzzles me slightly about the (awesome) science system is that if you take a crew report from orbit, only the height matters, whereas EVA reports yield a different result for different biomes below. I personally think that the other way round would be more logical - sure, it makes sense to want reports from your astronauts as they fly over different parts of the planet, but to they have to get out of the ship every ten minutes to do so? They have windows after all, and surely better instruments on board. I'd have thought an EVA report from Kerbin orbit would be mainly a test on suit function and effects on the Kerbal body, which would be the same regardless of whether the brave kerbonaut sees blue or green when he looks down.

I also think that EVA (when not landed on Kerbin) should maybe only be available after researching the 'Space Exploration' tech, but this could very well be planned anyway. Maybe Kerbals could eventually get an older-style spacesuit model until you unlock EVA-capable ones.

Sounds good to me!
