Investigate Adding Telemetry for Renames + Back Compat Done By the Generator

We can possibly create some metadata file that lists the renames that occurred. Possibly use a schema.

Start by locating the generator and reviewing how renames and backward compatibility are currently handled. Investigate whether a metadata file and schema can record the renames; document the viable design and its implications for generator behavior as the outcome.
