   > So, how do we continue from here? Do we have enough implementations now to 
start a vote? Or what is still missing?
   
   Thanks @JFinis! I think what's needed now is to have the PoC engines each 
write a file with the new ordering (perhaps `alltypes_tiny_pages.parquet` from 
parquet-testing), and then have a query engine (one of Spark, Datafusion, 
DuckDB) do a query like 'select * ... where float_col is NaN' and show that the 
physical plan uses the new stats and results in no pages being read. (Perhaps a 
`NaN` could be introduced in one page). This would demonstrate interoperability 
and utility.
   
   After that, I'd probably kick off a thread on the dev list to see if there 
are any last concerns before holding a vote.
