from my previous question, I can not config in dendron.yml to set private (not published) a partial of hierarchy with the

siteHierarchies

and

hierarchy

combination. Now, I've just found that I can simply put the key

published: false

into the frontmatter of

grand-child

node. Then the partial hierarchy starting from

grand-child

node is now set to not published, as my expectation. So I wonder what's the use case of the combination of

siteHierarchies

and

hierarchy

in

dendron.yml

, wrt the fact that the key

published

in the node's frontmatter offer the similar behavior?
