   I agree with your analysis, @szlta. I am surprised `PartitionsTable` does 
not use `Partitioning$partitionType`.
   
   I'd do the following in separate PRs:
   - Rename conflicting columns in old specs in `Partitioning$partitionType` as 
[discussed](https://github.com/apache/iceberg/pull/3411#discussion_r821845093).
   - Use `Partitioning$partitionType` in all metadata tables.
   - Consider adding `partition_spec_id` to metadata tables like `data_files` 
and `partitions`.
   - Consider reusing equivalent columns with column IDs during spec evolutions.
