Mine is filled, and i have recently travelled to UK severallt, almost 9 countries in European Union with the Schengen and no one ever questioned me "in 2016".
I have gone to several countries even in Africa, Brazil and Asia i filled that section in 2012 FYI.
No one has ever asked me about it, the only question i was asked is why i indicated "student" in the professional but not next of kin. its coz when i was applying i passport i was a student.
I dont think there is cause to worry.
I work so I can afford the amount of alcohol required to continue going to work
