    Mark debug flags which should be implemented differently
    
    I somehow missed the additional SLOW_BEREQ getting in (could be that this was
    during my vacation). I think we should avoid adding behavioural changes by
    special cased debug flags whenever we have better options, and in this case the
    better option are filters.
    
    Which, in this case, would come with #4035, a PR which ironically now needs
    additional attention just because of these changes.
