You get all the points for cooking up theories with the at times very limited info you have!

That post you mentioned with the theme of converging timelines and the past-present-future being one and what if someone existed above that separation etc. is a text that is still being analyzed in the fandom. It could be a meta way of introducing as canon the multiverse we're working with (all the LIs timelines being overlapping but separate), it could be a way of hinting at future plot developments, or something else.

You do still get very important basic info from the part of the mainstory you still have to play through (including anecdotes and world underneath), so you still have some fuel to add left
