I’m not sure how this could be avoided; but it seems like there’s a very strong pressure toward this ending up being a exercise in agonizing about uncertain future information rather than being reflective and selective about documentation if one moves from concept to actually trying it out.
“Write up just the important stuff; manageable length please” is more or less exactly what’s required of a memoire or a biography; but both of those are written after history has provided at least some context for events and enough has happened or failed to happen that deciding what is important is at least achievable in principle if not necessarily easy.
Doing that without the benefit of hindsight means a lot of attempting to guess what will end up being relevant in the context of things that haven’t happened yet.
