The URI spec says that the meaning of fragment identifiers depends on the Internet media type registration, but what didn't happen was to update BCP 13 (Internet media type registration procedure and template) to ask about how the registered  type interpreted fragment identifiers.

Well, ietf-types is important from a functional standpoint, but I don't know that it should be used to discuss the document itself. That sort of coordination should happen on apps-discuss and the URI list, I think.
