Why did scholars begin a critical Vatican edition of the Ordinatio in 1950?

Scholars began a critical Vatican edition of the Ordinatio in 1950 primarily to reconstruct the work as John Duns Scotus originally intended it.

Because Duns Scotus left the Ordinatio unfinished upon his abrupt departure from Paris, early versions were completed by his pupils, who often substituted his original text with student reports known as reportationes examinatae. The ongoing Vatican project aims to restore the text by incorporating all of the author's own corrigenda, or corrections, ensuring the work reflects his authentic thought rather than the imperfect forms in which it was previously circulated.1
