   Missclicked 😢 
   
   What I was trying to comment:
   Sadly I don't have enough time to properly review the PR, but I remember 
that we had issues with the partition evolution in the past when @szlta tested 
the Hive metadata tables. IIRC the issues surfaced when we changed from (a, b) 
partitioning to (a, c).
   See the relevant PRs: 
https://github.com/apache/iceberg/pulls?q=is%3Apr+szlta+partition
   
   The issues are handled on Core level, but it might worth to add some checks 
for edge cases too. Like:
   - Removed columns
   - Readded columns
   - Partition evolution
   - Schema evolution
