Unlike #630 (which merely implemented the then-stabilized core:…:Error on types), this would be a breaking change (spooling for #566), but contributes to the idiomatic usability of our error types because all conversions through core:…:Error are thus available easily.
This is "only breaking for implementers of the trait" – that's not a thing in semver, but can be a relevant piece of changelog information if all our changes for >>0.6 are.
