Let's wait for the big v0.50.0 PR to merge which fixes clippy lints and generally changes a bunch, and then merge this on top. I don't want us to start changing more files here because it'll just introduce conflicts with that rather big change.

Just FYI this is done now and so this PR can be rebased as needed shouldn't be a problem to merge :)
