I think Joe's point is about the perennial discussion whether hierarchy is better than tags. It's as old as software or as old as people started categorizing things. Some early databases were hierarchical KV stores. Email clients and services go through that too, is it better to group messages by tags or have a single hierarchy of folders?
> English absolutely has namespaces
Sure, we can pick apart the analogy, after all we're not programing in English unless we write LLM prompts (or COBOL /s). Then if English has namespaces what would you pick lager.flat.alcoholic or alcoholic.lager.flat or lager.alcoholic.flat, etc? Is there a top-level "lager" vs "ale" package, with a flat vs carbonated as next level?
