The short answer is: because ISO 639-3 says so (or, rather, fails to say so).

In addition, “German” is not considered a macrolanguage, according to ISO 639, nor is ‘swg’ considered to be enclosed by it. BCP 47 does not indicate nor attempt to indicate all possible relationships between languages. Clearly, on some level, more “macrolanguage relationships” could be defined. But these generally do not convey additional utility for the uses to which language tags are mostly applied and the additional complexity of macrolanguages is something that generally this group tries to avoid.

Internationalization is not a feature.
It is an architecture.
