All I can come up with is fan pandering - they think that everyone will go "aw" and think it's romantic.

It does seem that way, doesn't it? And yet they were doing so well--with a couple exceptions--at keeping the destiny and twu wuv in the background.

Paring down all of the mysteries and intricacies of multiple universes/timelines into "who does Peter bang it needs to be a specific Olivia" bullshit.

Yeah, it really does feel like this whole complicated universe and problem has been smooshed and strained into baby food-level plot. Ugh.
