I should also add that I am not an apologist for communion-in-the-paw at all (I think it should be abolished), but I don't believe your statement above was completely true prior to the Council.
Deacons were licit ministers of Holy Communion prior to the Council. They were considered "extraordinary" ministers, but it was permitted for them to be deputized by a priest to distribute the Eucharist. Also -- as far as I have been able to determine -- deacons' hands were not anointed or consecrated during their ordination. (Correct me if I'm wrong on that point; I do not have the 1962 Pontifical Missal and have not found the 1962 rite of diaconal ordination online.)
pre-council, during-council, post-council, regardless of when it was or is done in the modern era, or how, or by the authority of whimsoever, unconsecrated hands touching the Most Holy Sacrament of the Altar was, or is, outside of a very narrow set of unusual curcumstances, an abomination, a desecration, and the height of irreverence to God the Son. Protestants love it because Catholics should hate it but many don’t!
