Oh, yeah, I get what you're saying, and I'm not surprised at all. But what I meant was, the intentionality and reasons - Doylist explanations, that is - for how a story came to be the way it is are interesting in their own right, but still ultimately separate from whatever is presented in the finished work. Death of the author and all that. Regardless of why a discrepancy or contradiction appears in canon, making fanfiction, or more of the canon such as sequels, is bound to explain it in verse: without breaking the fourth wall.

In fanfiction, that might be a spackle fic that introduces some complicated sequence of events; or it might claim that Watson's wife had multiple names in Sherlock Holmes because he lied carelessly in his memoirs, or that eps of TNG repeatedly state that nobody in the Federation has encountered a similar situation even though it's exactly like something that happened on TOS because Kirk's logs were heavily redacted for security reasons.
