IIn master, `GetMapValue` nullable is always true; https://github.com/apache/spark/blob/cf133e611020ed178f90358464a1b88cdd9b7889/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/complexTypeExtractors.scala#L371 But, If input key is foldable, we could make its nullability more precise.
