Yes, and moreover, they just add a shared secret in the computation of the initial root key, it cannot be worse in this case.

it's good. think of it like adding a different kind of lock that requires a different key (method) to open up first. at worst it's no less secure than before. If it works as intended it's a huge disincentive for anyone collecting encrypted data with the hopes that a quantum computer may break encryption the "old" method in the future.
