Shouldn't this get a dedicated nsmul field now?
There was a problem hiding this comment.
They get one for free, which is the naive one defined by induction. One should only add one by hand if there is a risk of diamond, i.e., if we ever consider sesquilinear forms over naturals or integers. Sesquilinear forms over naturals don't make sense, so there is no issue here. There is an issue over the integers, so we should probably add a gsmul field, yes. I'll do it in #7255.
