Meltano deeply integrates with plugins like dbt/airflow/superset, right now thats done by building features inside meltano core (e.g.
Superset meltano core logic). The EDK is looking to pull that logic out to make it easier for developers to add custom functionality and deeper integrations with other tools wthout having to know the internals of meltano core. Also it allows developers to write different versions of functionality based on their needs. Check out
https://github.com/meltano/meltano/issues/6130#issuecomment-1224474108. Obviously this is still in development also. cc
