Ah yes . . . a historical relic that no Catholic bishop or theologian today pays one bit of attention to.
If you read any modern Catholic bible with the nil obstat and imprimatur (ie, one that isn't a museum piece), you'll see the thing accepts "modern scholarship" whole cloth. And we have been told by one of the most orthodox and conservative Catholics on this forum that the Catholic Church's doctrine of "Biblical inerrancy" still leaves the way open for "modern scholars" to have the final say on practically anything.
If so, their loss.
"...The Professor, following the tradition of antiquity, will make use of the Vulgate as his text; for the Council of Trent decreed that "in public lectures, disputations, preaching, and exposition,"(29) the Vulgate is the "authentic" version; and this is the existing custom of the Church. At the same time, the other versions which Christian antiquity has approved, should not be neglected, more especially the more ancient MSS. For although the meaning of the Hebrew and Greek is substantially rendered by the Vulgate, nevertheless wherever there may be ambiguity or want of clearness, the "examination of older tongues,"(30) to quote St. Augustine, will be useful and advantageous. But in this matter we need hardly say that the greatest prudence is required, for the "office of a commentator," as St. Jerome says, "is to set forth not what he himself would prefer, but what his author says."(31)..."
