I am not sure which recent thread mentioned this issue at least in part, but there are some canonizations or beatifications of the Novus Ordo that would appear to have been (at least in my opinion) where it perhaps "got it right."

Here is a list:

1) Padre Pio
2) Juan Diego
3) Maximilian Kolbe
4) Louis Martin
5) Zelie Martin
6) Martín de Porres
7) Peter Julian Eymard
8) Hildegard von Bingen
9) Juan de Ávila
10) Juan Macías
11) Elizabeth Ann Seton
12) John Neumann
13) Katherine Drexel
14) Kateri Tekakwitha
15) Rose Philippine Duchesne
16) Solanus Casey
17) Margaret of Castello
*(18) Gregory of Narek (declared a doctor by Francis but was thought to have died outside communion with Rome although maybe ws technically if he actually professed and accepted the Council of Chalcedon)

If there is a state of sede vacante right now since 9 October, 1958, none of the above named persons is actually canonized or beatified. Also there would only be 29 declared doctors of the Church with St. Anthony of Padua as the last one so declared. 

Martín de Porres and Peter Julian Eymard were canonized in 1962
Andre Bissette The miracle worker from Quebec would be a legitimate canonization

If you count John XXIII and Benedict XVI as legitimate popes that is. Thank you. I forgot about Br. André Bessette. He was great promoter of devotion to Saint Joseph. 

Rose Philippine Duchesne is beatified. She has a feast with proper collects in the Archdiocese of St. Louis. See the appendix in the altar missal.

And no female Doctors, which is an abomination ... with all due respect to St. Therese and St. Teresa.  EVERY saint "teaches" us something.  Like most NO conanizations, this was politically driven.  We have these DEI Doctresses from a Vatican that was woke ahead of its time.

Their decrees of canonization are meaningless. They don't tell us anything about a person's sanctity one way or the other. They're like the canonizations of Greek orthodox, for example.
