Python rhinoscriptsyntax equivalent of "RebuildMeshNormals"?

I see rs.UnifyMeshNormals, but not Rebuild. There is the RhinoCommon Mesh.RebuildNormals method, but maybe there should also be a rs shell made available (unless I missed where it is…)?

Something like this:

def RebuildMeshNormals(meshID):
    mesh=rs.coercemesh(meshID)
    mesh.RebuildNormals()
    sc.doc.Objects.Replace(meshID,mesh)
