Looks like this was due to this PR: #188

FWIW, in a separate project, I vendored coinbase/kryptology and modified the lines such that:

And then I updated that project's go.mod to use it:

// kryptology has been archived, replacing with a vendored copy which has been modified:
// HashToCurveG1Svdw -> HashToG1
// HashToCurveG2Svdw -> HashToG2
replace github.com/coinbase/kryptology => ./vendorlibs/coinbase/kryptology
