The original Cgo code did allow both. The maintenance burden or providing both for the Go implementation would have been far too onerous, so the column-major implementation option was remove from the Cgo wrapper for parity. I don't think the docs are buried; that is the first place people will look in general. FWIW The choice between rm and cm is difficult; all of Go is cm. All of Fortran is cm (also any GPU code). We've had this discussion internally and probably if we did it again, we might have chosen cm, but then we'd get people complaining that they can't represent matrices in source easily.
