Does/could this support syntax to paramitize identifiers safely?

https://www.psycopg.org/docs/sql.html has this useful feature where tables, schemas, etc can be safely parametrized and added to a query. 

```python
query = sql.SQL("select {field} from {table} where {pkey} = %s").format(
    field=sql.Identifier('my_name'),
    table=sql.Identifier('some_table'),
    pkey=sql.Identifier('id'))
```

is this supported or on the roadmap?
