Hi! Current implementation of FrodoKEM present on liboqs is based on the proposal for the first NIST PQC Standardization Process. After the selections made by NIST at the end of this round, the FrodoKEM team made important modifications to the submission: the NIST specification became the one named as "ephemeral" in which a salt is not included (and was renamed to eFrodoKEM). A new variant called FrodoKEM was constructed, which is suitable for applications in which many ciphertexts might be produced relative to a single public key, and includes further changes to address IND-CCA concerns.

Since FrodoKEM is recommended by a number of standardization bodies beyond NIST (is on track to become an ISO standard, appears as an internet draft, is recommended by agencies such as BSI), I believe it would be interesting to include both variants as part of liboqs capabilities
