   > Regarding q28 slowdown from PR description -- I suppose it's not a stable 
slowdown, and just a result on single benchmark run (since the regexp over 
`Referrer` field in the query doesn't seem to produce high enough cardinality 
to skip partial aggregation)?
   
   That is my understanding too. I also have high hopes that the StringView 
work will make that query in particualr faster as well
