needs changelog entry, otherwise LGTM

This is great! Please add a changelog to capture the enhancement

Do you know if users would use this output to create their configs? If that is the case, would this break their flow?

I do understand that this is nice to have, but would like to document what is the components command for (it's purpose). If it is only for info only and debugging then let's document that the output is not intended to be stable and programmatically used.

They shouldn't.

Good idea, I added a long description to the command to make it clear.

This is now ready for the next review.
