thiserror is more lightweight and we don't need most of the Snafu magic. As a consequence, backtraces become only available using Rust nightly (cargo +nightly test --lib --features backtraces) but we don't need them often.

Currently blocked by dtolnay/thiserror#99 if we want to avoid renaming the field.
