Remove unused args from functions

`#[instrument]` suppresses the unused arguments from a function, *and* suppresses unused methods too! This PR removes things which are only used via `#[instrument]` calls, and fixes some other errors (privacy?) that I will comment inline.

It's possible that some of these arguments were being passed in for the purposes of being instrumented, but I am unconvinced by most of them.
