I was hit by this yesterday too. 😄
And I've realised that Debug for BTreeMap::{Keys,Values} wasn't formatting just keys and values respectively, but the whole map. 🤔

Fixed #41924

I'm not sure why the removal of .inner for BTreeMap is necessary, but apart from that it looks good to me. Can't r+ though since I'm not a member of the rust team :)

As far as I understood, the .inner is an iterator on the full map, while self implements an iterator on just keys/values. Long story short, {:?} on Keys/Values was printing the full map, not just the keys/values.
Sorry about the r?, now I get how it works. 😄
