   Want to strongly highlight for folks reviewing (@kevinjqliu + @Fokko?) that 
I've **not** changed `WRITE_OBJECT_STORE_PARTITIONED_PATHS_DEFAULT` to `False` 
even though it's a similar change that intends to improves object store 
performance. I'm very open to discuss/change this (I'll update this PR name + 
description or put up a new one if so).
   
   So do we want to do this? My thinking was: after reading through 
https://github.com/apache/iceberg/pull/11112 it seems there was a strong case 
for supporting partition values in paths. When I thought about that, I realised 
that users might be relying on storage layout and files constituting partitions 
lying in the same directory - maybe just so that they can inspect storage to 
see how their files are *actually* laid out at a given point in time, 
especially in the context of partition evolution.
   
   On the other hand, maybe we should make this change to *discourage* reliance 
on file storage layout.
