We once had a consultation with a Drupal Agency when we moved from D7 to D9. They explained to us that "blt artifact deploy" can be used to fill a git repository that is then copied to the server for hosting using CI/CD.

With BLT not being maintained anymore, what's the successor for this kind of workflow? Is there a replacement to handle this? Should it be done on a per project basis and artifact deploy isn't a valid approach anymore?

Would like to get some insight on how others do this and appreciate any feedback or hints to tooling or workflow to learn.
