That's why I said *almost* virtually identical. Please, don't conflate
"almost virtually" with "exactly" on that very particular context.
Furthermore I was referring to the specific case at hand: the
practical significance of copyright enforcement for permissive
licenses. None of the legal technical differences you pointed are
relevant for that matter: it's a common practice to make the due
attributions in derivative works, even when based on public domain;
so the unique guarantee one gets with a permissive licensing, rather
than releasing into public domain, has no practical expressiveness.
