Well, true.. the Hash_DRBG hashing algorithm remains. But it's rather likely that previous FIPS validations occurred utilizing the actual backdoored and deprecated algorithm as an input to the Hash_DRBG, rendering it's security properties suspect.

In NIST SP 800-90A Rev. 1, the HASH_DRBG section has been significantly updated to that effect.

For instance, Appendix E: (Informative) Revisions.

Section 10: Section 10 now includes a link to the DRBG test vectors on the NIST website. Sections 10.1, 10.1.1 and 10.1.2 now include short discussions about selecting hash functions to support the DRBG's intended security strength. The Dual_EC_DRBG has been removed, and section numbers adjusted accordingly.
