It seems like the number of shown language links at nowiki is somewhat small given that most Norwegians reads Danish and Swedish without any problem, and that we now have three languages at school. Add to that Faroese and Islandic, which is pretty close, and some extra neighbor language for the fun of it, and the list of 7 is full. Add a few to 10-11 -ish so people stop complaining?
If the system keeps adapting to an increased number of preferred languages, that would perhaps be better. I'm not quite sure how I should interpret the numbers from How many languages are shown in the compact list? Perhaps a better explanation in the FAQ is sufficient! =)
