In classical music biographies:
A rough translation of the current situation:
"Again and again people infoboxes are created in the German Wikipedia. They are also regularly deleted on the grounds: "DE:WP wants no person infoboxes". Such a statement cannot be clearly determined from the many discussions on the topic, there is even evidence of a contrary opinion of the community, is hereby asked whether infoboxes are wanted in persons articles or not.
Currently in the German Wikipedia there are infoboxes for athletes and a few other groups of people."
That RFC was closed due to a lack of votes to start it. I don't know if the arrival of Wikidata has changed the perspective during the last 2 years.
Cheers,
