These are cases with source data issues (that we discussed). The final step of deserialization raises validation errors, because of which we don’t end up with a properly initialized instance.

Use cases which require a properly initialized instance include BibXML serialization and xml2rfc path detection.

Sentry should have events “Failed to reverse xml2rfc URLs for item …” reported.
