Question about the November 12 deadline

We noticed a change in the page Adding a privacy manifest to your app or third-party SDK that adds a deadline of November 12 past which invalid manifests will not be allowed in store submissions.

Does this mean we can no longer use old versions of third-party SDKs which lack a manifest? (The ones that were allowed because we had already shipped with them.)
