Review Comment:
   This may be a contributing factor indeed. I suspect that another factor is 
that filtered tasks use the default impl of `nextDocsAndScores` which adds some 
overhead compared to what we were doing before since it first needs to copy 
matching docs to an array before doing work on this array. I was keen on 
looking into the performance of filtered tasks in a follow-up, I worry it's not 
going to be easy to recover performance.
