Remarks

Upstream's DATE_FORMAT is "[year]-[month]-[day]" (databento-rs/src/historical.rs:184-185), which is exactly Iso. Registering this converter for LocalDate also covers LocalDate?: System.Text.Json unwraps the nullable and hands the non-null case here, answering null itself for a JSON null — which is what last_modified_date carries when a day's condition is Missing (metadata.rs:300-301).
