Probably a bit and in reaction to a so-called traditionalist who has his own manner of changing the Mass to fit his own agenda. But as you will see at the end which I underlined, there is a suggestion which is a long ways from “God Bless you”. If the purpose was to invoke a blessing, the Church would have clearly said so. Instead, it was clear that it is to be a communication that the Peace of Christ be with them.
However, the GIRM is clear on the purpose which is to express communion and charity. The prayer the innovator uses is an intercessory prayer which is a request for an action of God vs. responding to the call to express peace, communion and charity on behalf of Christ.
- The Rite of Peace follows, by which the Church asks for peace and unity for herself and for the whole human family, and the faithful express to each other their ecclesial communion and mutual charity before communicating in the Sacrament.
As for the sign of peace to be given, the manner is to be established by Conferences of Bishops in accordance with the culture and customs of the peoples. It is, however, appropriate that each person offer the sign of peace only to those who are nearest and in a sober manner.
And then says later in paragraph 154:
The priest may give the sign of peace to the ministers but always remains within the sanctuary, so as not to disturb the celebration. In the dioceses of the United States of America, for a good reason, on special occasions (for example, in the case of a funeral, a wedding, or when civic leaders are present) the priest may offer the sign of peace to a few of the faithful near the sanctuary. At the same time, in accord with the decisions of the Conference of Bishops, all offer one another a sign that expresses peace, communion, and charity. While the sign of peace is being given, one may say, Pax Domini sit semper vobiscum (The peace of the Lord be with you always), to which the response is Amen.
