I've done Tahoe-to-Tahoe migration assistant moves between machines in recent months. No issues with login keychain migration.
But that’s not backup restore? I’m thinking Time Machine restore on a new Mac when old one is no longer working. Or when the old one had to be wiped and restored.
Migration Assistant uses the old Mac, which can unlock its login keychain and allow the keychain items to be copied.
