 I think it's a fine recommendation about, but I think it's really fulfilled in the certificate of baptism. The certificate of baptism should say it was baptized in the name of the Father and of the Son and of the Holy Spirit with flowing water, and then the priest would sign it and have the address of the church so that any update can be made to the register for marriage, etc. But I think a lot of what you're describing as a very fine thought is already captured right in the certificate of baptism and in the registry of baptisms.
