I largely agree with your list and what you've really shown is just how little like D&D, D&D has become and how more and more it's trying to be a tabletop cRPG, and also why I have had had no interest in new editions of D&D since 3.0e.
However, I don't agree with point #4 or #5 at all, as the 1e AD&D was not actually super lethal and one of the reasons for that is that monsters rarely had good THAC0 or the ability to deal a lot of damage. The adventuring day could continue despite depletion of resources because on average PCs had overwhelming advantages in a fight, and fighters were strong characters in large part because they could easily get AC high enough to make hit point loss from mundane combat not a serious factor in potential character death.
I also for the same reason generally don't agree with your "Honorable Mentions" save possibly the potion miscibility table in some variation.
I partially disagree with #9. Darkvision did not exist in 1e AD&D and to the extent that creatures could see in the dark, so could PCs. "We can't see!" or after about 3rd level "We're afraid of the dark!" was never a big part of the 1e AD&D experience and instead comes out of a much more modern mindset that is the modern version of DM vs. PCs antagonistic play. "Oh your torches are burning out and you'll be helpless MUHAHAHAHA!" is not "old school" no matter what anyone says. "Do you have a way to see?" on the other hand is old school. The 1e AD&D experience comes from "the imagined reality matters even in the details". Things have tangible shape and size and weight. You can touch them and they have a feel. The air has a smell. You have real hands and they can only hold so much and a real backpack that when shouldered makes you go, "Ooooff". That's 1e AD&D feel.
