Other than that, I don't see any technical problems with getting this information not from the type attribute but from somewhere else like a kernel attribute (which would probably be the same sg map but attached to a kernel?).
It is not necessary to require all operations to have a same mapping rule, since they have different semantics. But it requires each op has exactly one mapping rule.
