**Describe the bug** ProjectionMask::columns in parquet allowing selecting columns, this is created in https://github.com/apache/arrow-rs/pull/6871 . However, this method is bug prone. **To Reproduce** Assume schema: ``` { a: int, aa: int } ``` Select "a" will also making "aa" selected. **Expected behavior** I think the interface should be deprecated. Outside should pass explicit the require path. Or inner should receive the path. Parquet allows "a.b" column, so I don't think dot is a good way. **Additional context** No -- This is an automated message from the Apache Git Service.
