Review Comment:
I will try to include it in my next PR, which should be tomorrow hopefully.
just for clarity do you want to implement something like this for other
supported file format
```
fn supports_repartition(&self, config: &FileScanConfig) -> bool {
!(config.file_compression_type.is_compressed())
}
```
and original for csv.
