   Hi,
   
   We've been using auto-generated field_ids from `parquet::schema::Node` for 
querying nested types. When we updated to Arrow 7.0.0, we've noticed this field 
is not set anymore. 
   
   I've checked the discussion in the 
[PR](https://github.com/apache/arrow/pull/10289) and in the [JIRA 
ticket](https://issues.apache.org/jira/browse/PARQUET-1798), but I couldn't 
find the reasoning behind removing auto-generation of field_id. Is there a 
workaround which we can utilize to identify Nodes with the current 
implementation?
   
   Thanks!
