What it does

This class serves as a source model for DHL non-document shipping methods in Magento 2.

It's used to provide shipping method options specifically for non-document packages (like physical goods) through the DHL carrier integration, differentiating them from document-only shipments.

Developers would use this when configuring DHL shipping options in the admin panel or when programmatically filtering shipping methods based on content type.
