Our usually well-informed friends at Messa in Latino have just posted the information that their highly placed sources in the Vatican have informed them that, "in early January," a document of the Congregation for Divine Worship will be published making known a list of seven saints whose optional commemoration would be added to the Universal Calendar of the 1962 Roman Missal (the "Extraordinary Form" of the Roman Rite).
It should be noted that, when Francis suppressed the Pontifical Commission Ecclesia Dei, that dealt with matters concerning the Traditional Mass, earlier in 2019, all its competencies (including those mentioned in Summorum Pontificum) were included within those of the Congregation for the Doctrine of the Faith (with no exception for liturgical matters), so we would have to wait for the supposed Divine Worship document to see the basis for it being published by that dicastery (dedicated to the New Mass), and not Doctrine of the Faith.
The Benedict XVI letter accompanying Summorum Pontificum itself made mention of the addition of saints to the Traditional Roman Calendar. Which could also be interpreted positively in the sense that the Latin Mass is living and is here to stay for good, even in the eyes of the Vatican. However, it would be problematic for the bureaucracy of Divine Worship (if confirmed as a Divine Worship document), intimately connected to the New Mass, to be tinkering with the Traditional Missal: it could be a Pandora's Box of problems. Cardinal Sarah is there now, but even he is a tiny minority in his Congregation.
