When you add the data_collection_permissions property in manifest.json, addons-linter reports the error: The "data_collection_permissions" property is reserved. (DATA_COLLECTION_PERMISSIONS_PROP_RESERVED)

But when you publish an extension without the data_collection_permissions property, you get the warning:

The "data_collection_permissions" property is missing.

Avertissement: The "/browser_specific_settings/gecko/data_collection_permissions" property is required for all new Firefox extensions, and will be required for new versions of existing extensions in the future. Please add this key to the manifest. More information at: https://mzl.la/firefox-builtin-data-consent
