I'm on board with all of those things being available, but limited or rare. I subscribe to the philosophy that if everyone is special, no one is. Healing should be special. It should be something that some people have, and that they have at some times. Not a default expectation. Not a right.
The outcomes being that it should be fairly normal and okay for PCs to be at less than optimal health for extended periods of time, and that there should be a large difference in recovery rate between a party with a healer or a healing item and a party that does not have those things.
This x 100.
Perhaps the answer to the question of, how do we fight a CR+2 creature when we are wounded? should be, you don't.
Many of the really cool situations and creative solutions to problems experienced in old school play come about because the party can't just bulldoze through everything head-on and expect to survive.
Too much healing and all you end up with is a fight game. Best reason ever given for being a hammer and treating every obstacle as a nail- BECAUSE I CAN.
