Well,
It is a flagship mission they're talking about on the scale of Cassini, and that had a lander. Granted Huygens could land with a parachute which won't be an option on Europa. I did also mention the possibilities of micro rovers which could hop around. They would be small enough to not require extensive fuel to land. As for the value of being on the ice, Galileo imaged what looked like subsurface material, perhaps brine, that had pushed up through fresh cracks. How exciting would it be to examine that for microbial life?
Technology for everything is constantly getting smaller and lighter. By the time something like this mission launches we may well be able to do far more than we can now.
