Well, I decided against passing in the full configuration as it feels a
bit like a layering violation: the other code really is about the fetch
itself, while this code here is only about display logic. So passing in
the `fetch_config` felt weird to me, even more so because we continue to
only need that single value at the end of this series. I do see your
point though.

Given that none of your other comments require a reroll I'll leave this
as-is for now. Thanks for your review!
