Isn't this an edge-case?  Even if my primary language is German, I will
write the module documentation in English first.  By doing that module
developers ensure that a module (including its documentation) is actually
usable for all Drupal users, speaking all kind of different languages.
Also, by doing that I often determine phrases that may be hard to translate
into other languages, including German.
