Description

Proposed logic:

1.  Add flag where appropriate for supports dictionary replacement if there is a possibility it can be used.

2.  Only add compressed buffers when requested.

 

Reading should validate enums are in range AND implementation supports them.

Research direction

Start with the linked migration documentation and the Java subtask to determine the Java-specific scope. Review how feature values are currently handled, then verify that the Java implementation uses feature enums, validates their range and support, and only adds compressed buffers when requested.
