Metadata deletion not considering child metadata (providence 2.0.9)

[thCAgh]

Lets say i create this metadata tree

ParentA (container)
  |> ChildA-1 (text)
  |> ChildA-2 (container)
    |> ChildA-2-1 (text)
    |> ChildA-2-2 (text)

If using the UI, i delete ChildA-2, that record in the DB gets flagged as deleted=1 and not showing the entire tree in the UI anymore, but the ChildA-2-1 and ChildA-2-2 are still there.
If i try to remove/purge the deleted items using caUtils i get the same outputs and totals every time i run the command, looks like nothing is being "purged" at the end.

If i open the DB directly and try to delete ChildA-2 (container), i have consistency errors from DB, indicating i need to delete ChildA-2-1 and ChildA-2-1 before delete it.

I see room for two main improvements:

1. Somehow this "dependency" messages are not displayed by the caUtils purge-deleted command, it would be helpful to have it.
2. Deleting (in the UI) a container with metadata on it should not break "consistency". Perhaps avoided displaying a message or all the tree must be correctly deleted after asking confirmation to the user.
