I've created an issue on GitHub, although my description might be not that accurate. :)

db_to_form_package_schema() is _only_ used when you call it from your IDatasetForm plugin, it's not used internally by CKAN. It's purpose is to return a complete "default" package schema that you can then modify by adding your custom fields. So if there are fields that are part of packages in CKAN by default but are missing from db_to_form_package_schema(), that's a bug.

I realise this needs better documentation and examples, and also unit tests so that bugs like this one can't creep in, we're working on it.
