Absolutely. Me too. Ever since we first saw him first arrive at the Citadel, the audience discovered the intro sundial was an actual in-story thing...that we, the audience, were learning about the history of Westeros, the TV show, as if we were actually in the Citadel as participants.
There is also that Season 8 finally has a new intro of sorts. The very last thing Sam did at the Citadel after stealing books and documents was to look up at the sundial. I view the new updated intro as what Sam will add as contribution to historical record. In addition, there is that scene where Sam comments on the name of the history of Westeros master book. I can't recall the name, but he commented on how lame the name was. I have a feeling that as new Archmaester or whatever, he's going to rename that the book series name.
Then there's the old curmudgeony, arrogant Jedi Order, err Grand Maesters. They're all far too ineffective now and inflexible (and very "not gonna be my fault when something goes wrong!) Sam comes into conflict with the very problems of the current order through the unsanctioned Greyscale treatment, the diary of shits, not taking the dangers of WW seriously. Sam has to represent a new guard. Shit, even Qyburn represents, in some ways, the failings of the Maesters through all of Pycelle's snooty superiority.
Then there's Maester Aemon. On his deathbed, he spoke to Sam about once being in love, rejecting kinghood, etc. This part of my thinking is the biggest stretch, but I think we're supposed to take from it that tragedy will repeat itself but with Sam, Gilly and Little Sam. I think there's a strong possibility that Little Sam and Gilly don't make it out of those crypts alive and it becomes even more of a duty for Sam to take over the Citadel rather than become Super Master Lord of like everywhere South.
He had that line when leaving Old Towne about being done with reading all these books about "better men" not only indicating that he will now be an active participant, but also making commentary on the current state of those not better men residing in the Citadel.
My initial thought both after the episode and overall was yeah, Jorah's done. Totally done. But then I kept thinking that his receiving Heart's Bane and meeting Lady Mormont is kind of repetitive of Brienne being knighted and receiving Oathkeeper. Similarly, both arcs would be done, so they'd die, but I feel like D&D hate repeating themselves.
Instead, I think they're going to subvert our expectations. In Brienne's case, she's probably done-done. With the Mormonts, I think Lyanna is going to bite it instead. While Jorah has completed his redemption arc and has been rewarded for it, he's basically the Prodigal Son, and that part hasn't happened yet as it's more epilogue-y.
