That's exactly what we should not do. People who read German don't necessarily live in Germany, and Texinfo is not a general-purpose system for typesetting documents, it is a system for writing software documentation. Besides, which German are you talking about? There are several German-based locales, each one with its own local tailoring. So consistency in Texinfo is IMNSHO more important that fine-tuning the order to a specific locale and language.
