Leaving aside that the level of detail in my example doesn't exist in the ED galaxy, The Chronicles of Pern offer a compelling example for why those interested in paying for data on an Earth-Like World would be interested in paying for data on the rest of the system... and to the degree where information about the remainder of the system would be critically tied to the value of the ELW itself.
For those unfamiliar with the story, Pern is an earth-like where everything seems fine most of the time, but another planetary body in the system with a highly eccentric orbit that brings it close to the main star every 200 years or so (IIRC). When it is close its indigenous life thaws and makes the jump from the eccentric body to pern, where it is called "thread". The threads kill whatever they touch.
The survey team didn't scan the entire system, so the colonists who came to Pern were caught off guard by the first threadfall. It devastated their society, eventually resulting in a near total loss of their technological advancement (only a very small portion were able to evacuate the planet).
I guess where I'm going is full system scan bonuses would make a lot more sense to me if there were things we could discover that could negatively impact the value of any high-value bodies in the system. In which case: the bonus ought to come with an additional change where data on an ELW becomes less valuable if there is data on a neutron star on file in the same system (whether as part of your own data or what a previous pilot has already turned in). That would make it interesting, especially if we could voluntarily drop specific data before turning everything in...
