Can you elaborate on your use-case for retrieving all components of all projects? Are you exporting/importing them into a BI solution?

Can you add ACL checks / filtering, similar to

Hey guys, just to chime in my use case here, this would be useful since we have a lot of microservices (which are their own project), that we group with a parentProject

It would be great if either the parentProject automatically includes components from its children, or that we could list all components so that we can keep track of all packages we are currently using.
