I had an idea previously when having the same thoughts as you. When we boot up the game for the first time ever or in a long time, we get promoted to visit Ikora to pick up aspects and fragments by “meditating”. I’m fine with the concept, but to spend Glimmer, kneel and leave with power is a bit underwhelming. I think Ikora and her Hidden could repurpose or derive a device based on FWC machinery, where our consciousness would whether the device and run through memories and mission logs of events that have already happened, to help us for the wars to come. On a weekly rotation, we have the opportunity to replay 3 “vaulted” missions on regular and heroic difficulties, for your standard rewards but to learn weapon patterns of gear from that period of the game no longer accessible.
