For example, autolabel might emit:
mwapi.errors.APIError: badid_rvstartid: No revision was found for parameter "rvstartid". -- See https://hu.wikipedia.org/w/api.php for API usage. Subscribe to the mediawiki-api-announce mailing list at <https://lists.wikimedia.org/mailman/listinfo/mediawiki-api-announce> for notice of API deprecations and breaking changes.
Instead, we should increment a "missing revision" counter, and report the total number at the end of the run.
