Which spec are you are referring to? We are using this specification: https://datatracker.ietf.org/doc/html/draft-irtf-cfrg-bls-signature-04#section-2.3

Step 4 of the procedure is to hash the salt, which is the line in the keygen function you referenced.

Oh, I noticed only now I was checking different versions and hashing the salt looks it has been added in the version 04 (see version 03). It is not there before. And bls_sigs_ref follows the version 02 apparently.
Why has it been added?

This is not exactly right forum to ask this question:-) But on serious note, we just follow the spec, so... the issue is effectively resolved.
