Fair correction - I should have been more precise.
The point I was reaching for is a practical enforcement one: verifying that edges have actually been deleted from an opaque, continuously updated knowledge graph has no standardized technical mechanism. Regulators have audit powers, but graph deletion verification i.e, confirming that relational inferences are gone, not just that a node was removed has no established standard. Controllers can assert compliance in ways that are genuinely difficult to challenge in practice.
Ah, then I don't disagree.
