My `Accept-Language` looks like `en-GB,de-DE;q=0,8,…` and for some reason Notion:
- interprets this as me preferring German
- tries to retrieve a non-existent German version of the page
The HTTP semantics RFC[1] is quite clear that an unqualified value should be equivalent to 1.0, and I don't think content negotiation should ever prefer a non-existent resource to one that exists.
