Hi Joshua, I do not have a strong preference about the UUID type, but I would like the highlight, that the type is handled inconsistently in Iceberg with different file formats. (See: https://github.com/apache/iceberg/issues/1881 )
If we keep the type, it would be good to standardize the handling in every file format.

If so, why?
