Technically, the staff had already decided on having Behind the Scenes sections at least a year ago. However, it was a decision made during one of those typical ad hoc discussions on Discord we used to have, and because I felt that the agreement I got came at a whim, I was hesitant to implement it. In other words, I didn't feel confident there was official weight behind it.
With that having been said, I've always thought that having the BtS section would improve the quality and informativeness of our articles. My main concern is transitioning into it as these sections would inevitably demand greater standards than Trivia sections.
My idea is that BtS and Trivia sections be mutually exclusive, but that we don't mandate that all Trivia sections be replaced by BtS immediately. Otherwise, this would put too much pressure on us. Rather, when there is sufficient need or information to justify a BtS section, it should be used instead.
I disagree a little with this line "Trivia would encompass all IU facts that for whatever reason don’t fit in the main body paragraphs". Specifically, one of the main purposes of the trivia section as recommended by Fandom is to have place for users, especially inexperienced ones, to dump information that they think are noteworthy enough to include in the body but are not yet sure how. The trivia section functions as a place to note down information that should be incorporated within the body but which has not yet been so. A different and often simultaneous function of the trivia section is to provide OOU details that are significant but do not fit into the article. We do not have to follow strictly by Fandom's recommended usage, but any IU information that merits mention in the article at all should always be incorporated into the body in some way.
So, if we maintain Trivia sections, we should be clear that their function is to list IU facts that we have yet to find a way to incorporate into the body, rather than that just doesn't fit per se. I think the former is more or less the same as what Lacrosse meant. I just wanted to be clear that if IU facts don't fit into the body, we are supposed to be finding a way to fit them into the body eventually rather than leaving them permanently in the trivia section.
As for BtS sections, if we are to begin having them, I just wanted to be clear that they should not be written as a list of bullet points but in complete prose. I certainly do think that they would help explain gameplay mechanics behind certain concepts of our article much easier and also facilitate better organization of OOU content. Currently, for trivia, we have them haphazardly organized. Tenses are often mixed up because editors past and present aren't sure when a point is OOU or IU, and sometimes they can be both. IU and OOU points also tend to not be segregated, resulting in them being mixed together or place one after another.
So all in all, I'm glad someone finally took the initiative to propose this because I was hesitant to really push through with this before, not being confident that if people did agree, they weren't just going with the flow with me.
