Hyukjin Kwon commented on SPARK-59321:
--------------------------------------
Resolving as Not A Problem. Protobuf schema conversion recurses over a finite
descriptor (bounded by the schema, not by input data), and recursive message
types are already rejected by default, so there is no unbounded recursion to
guard against here; the proposed bound added no coverage and could affect
legitimate deeply-nested non-recursive schemas. See apache/spark#58602.
