I don't know why it's still hard, but I can tell you, from the perspective of trying to prototype something, I would love to not have to use it just to find out if this functionality I want to build is worthwhile. I don't want to have to create a client, get some keys, worry about refresh tokens, etc. I want to hit an endpoint with an easily accessible token and get some data. Make it so that the token is only valid for 30 days or something and then it requires moving to OAuth. But for prototyping stuff with curl and bash scripts, it's a giant pain.
