Surely the top-level structure here needs to be organized by key, not partition; else it's no better than an index per
partition.

I wouldn't necessarily be opposed to official topic branches at some point in the future, but I think it's premature
tospeculate about whether it'd be useful here. What is needed right now is design work, not code.
