Among these postings were references to priests doing Confirmations.
There is nothing new, strange or improper about this, depending on the circumstances.
Bl. Junípero Serra, as head of the Franciscans sent to evangelize California, was given the authority to confirm. It was a long walk or sea voyage for the Bishop of New Spain (México) to visit the missions.
More recently in area where the custom is to confirm at the time of baptism, the officiating priest, often a Vicar Forane (a sort of rural “assistant bishop”) is given faculties to do so. This also true in Eastern Rite Catholic Churches.
