I think it got better, but unfortunately I never filed a bug documenting the bloat, so it's hard to track down what changed, or if I was simply wrong. My recollection is that most of the bloat was a per-invocation copy of the panic code, including formatting of the error message. Class declarations are still heavy, cargo-bloat on the current druid-shell library is showing about 900 bytes per add_method, which can add up but is unlikely to be a major source of bloat.
