I think it's a good solution. The only known problem with that idea is that the common code has to live "forever" - as long as someone can use the older providers (or older Airflow version). The solution would be to introduce some explicit deprecation or versioning for provider dependencies - but that's not really possible due to lack of constraints for optional dependencies.
