This would basically make an entry in personalized result be handled as any other, no special personalized ranking.
I recently saw a post claiming site x which is a popular block, being the best result, when it is surfaced by kagi. And I had built up quite a few entries in my personalized results. So I wanted to try kagi without my entries, at least for a while. Only way to do that now is to delete the entries. A “normal” setting could make it stay in the list, so I could go back and fix personalized ranking later if I wanted to.
Now all my entries are gone, so building up the list again has to be done by memory.
