Dear typing-sig,

I've noticed recently that there is practically no support for type-safe ORM/ODM projections in the broader Python ecosystem.

I was under the impression that SQLAlchemy is moving in this direction with the 1.4 release:

https://docs.sqlalchemy.org/en/14/orm/mapping_styles.html#declarative-mapping-with-dataclasses-and-attrs

and:

https://docs.sqlalchemy.org/en/14/orm/mapping_styles.html#imperative-mapping-with-dataclasses-and-attrs

I have not used SQLAlchemy 1.4 yet so I can't report on the effectiveness of this approach yet.
