   This wouldn't be too difficult to fix. The problem before was that Parquet didn't have a UUID type annotation so there was no way to encode that a fixed was a UUID and correctly infer the schema. Now that this has been fixed, we could start using it. The larger issue now is that no processing engines can create a UUID type.
   
   I'm still leaning toward removing it from the spec because there is no support for it in engines. I think a better way to do what this was attempting to is to add support in processing engines first, then support it in Iceberg if we need to.
