grpc has been updated . But riot still uses Deprecated mesthods. Why not upgrade？

riot\data\client\main.go
`b := grpc.RoundRobin(r)

ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
// defer cancel()

conn, err := grpc.DialContext(
ctx, *reg, grpc.WithInsecure(), grpc.WithBalancer(b), grpc.WithBlock())`
