Its not like writing nicely commented and documented code is a complicated task, when done at the start of the project, yet very few open source projects manage it. Its not about the complication it is about the time, you have to get the time from somewhere and the people that have the info to do so also have other BM demands on their time, as well as RL.
Constructive criticism is always a welcome thing.
Of course, there's no way to get back the lore of the people that preceded whoever's in place now, but I made such a suggestion long ago, and while I might be wrong, it does not appear it was ever followed. Personally, I think that if it delayed NPC responses a little, it'd still be worth it. Though I was always in favor of there being more than 1 GM per faction to share the duties and responsibilities anyways.
