> An unwrap() is a dev explicitly saying this should always contain a value Isn't expect() supposed to cover that case?

  No it's the opposite. Unwrap() means the dev said this will never not be set. Expect() is saying if this value is not available exit the program with this user facing error message.

  expect() is like unwrap() but you can give a message as an argument.
