I look at it like this: Planetary landings? GREAT! Give explorers who want to land and check out planets the ability to do more detailed scanning and the like. I think that would be awesome.
I can also see it like this: Planetary landings? BOOOO! There is nothing for me to do down there!
I think some explorers will see it as a great opportunity to have more fun and more things to do other than just run around, scan a system, rinse and repeat. If you find a planet that is interesting, like say an earth like, then that would be pretty cool to land on. I mostly see the second thought for players that pretty much do everything else and stay within the bubble of known space. I think it will be a niche thing to begin with until FD, like you mentioned, put in the meat for planet side stuff.
