No, it's not an absurd claim. Lattice key establishment goes back into the mid-1990s, and was at one point a serious contender for the alternative-to-RSA/FFDH algorithm that ECC became. Modern LWE lattice KEM is approximately at the same point in its lifecycle (say, compared to original NTRU) as Curve25519 was to ECDH.
