   I believe your implementation will break this query (at least from ZetaSQL dialect path)
   
   ```
   SELECT DISTINCT val.BYTES
   from (select b"1" BYTES union all
         select cast(NULL as bytes) union all
         select b"-1" union all
         select b"1" union all
         select cast(NULL as bytes)) val
   ```
