Research direction
Start by reviewing the 0.16.0 reader's support for table versions 6 and 7, then investigate the listed partial update, deletion vector, and secondary-index features. Record every unsupported feature for tables written by 1.x, and verify that the resulting documentation clearly states the compatibility limitations.
