The Panopticon/Are all these footnotes involving the Barbara Wright Building necessary?

I've noticed that every single time the year 2016 is mentioned in regards to objects and characters from Class, this message is slapped underneath:

"In The Coach with the Dragon Tattoo, we see a plaque that tells us the Barbara Wright Building was completed in spring 2016."

Is this needed? What's the difference between saying a dragon came to Coal Hill in 2016 and saying a dragon killed a cleaner? Surely if someone wants to know why Class takes place in 2016 they can just go to the story page being sourced for the information, which should and probably will have this footnote.

With all these pages being created for just two episodes, one can just imagine that if it continues at this rate this message will be on hundreds of pages.
