Can you please direct me to the vote or discussion were proper nouns in Proto-Germanic were made forbidden? I cannot find one.

They're not forbidden, we have many of them. This just isn't one, it's a regular noun.
Putting a pin in that. Where is the vote/discussion on any reconstructed lemma relating to nationality being set to lowercase?
Talk to my lawyer, since you clearly want to be one.
