@pitrou, as I mentioned [here](https://github.com/apache/arrow/issues/50249#issue-4739960981), the current API is problematic because it does not provide a way to determine whether a value is null while iterating over a `BaseBinaryBuilder`. For example, `VisitValues` uses [this code](https://github.com/apache/arrow/blob/12b3eda46a69fbc2e7f6f9c52be345b678f4baae/cpp/src/arrow/util/hashing.h#L862-L867) to iterate over the builder's values, but with the current interface it has no way to distinguish null values from non-null ones. This makes it impossible for callers that need to preserve null semantics. -- This is an automated message from the Apache Git Service.
