Every map the export withheld WHOLE because a served read never carries it: a connector's header and environment-variable maps. The item is written with that map absent, so once served an import reads this list to tell an incomplete map from one the package never had, and names each one for an operator to re-enter.

Absence says nothing about what was withheld when the exporter predates this key; from an exporter that writes it, absence means nothing was withheld. |
