Forgive my ignorance. I still do not get why index must notice prefix change? The only reason I can think of is that we must make sure there won't be any user-modification in index outside the prefix. But that can be guarded from higher level (plumbings and porcelains) because index is allowed to have modification outside sparse prefix (auto-merged entries). -- Duy
