   Regarding the metadata table, why is it only limited to position deletes? do we anticipate a separate equality deletes metadata table too? This metadata table is at row level, like a source. For row-level deletes metadata, I am wondering if `delete_files` summary is good enough, which is similar to the `files` metadata table.
   
   I assume this position_deletes metadata table is to not related to the CDC read like Ryan suggested in the CDC. Otherwise, the metadata table should cover inserts, position deletes, and equality deletes.
