The headline is a straight up lie. As per the article itself, it was conceived of in 1966 and experimentally confirmed in 2020.

I love using magic items in place of house rules. It makes it easier for everyone when “house rules” are explicitly spelled out in an item description, and helps prevent players from being confused or surprised about which rules do and do not get enforced and in which way.

To contribute my own D&D 5e specific example: I like to have enchanted weapons that each have access to one or two battlemaster maneuvers per short rest. e.g. Quarterstaff of Tripping (trip attack) or Commander’s Longsword (Commander’s Strike). To keep it simple, I use the weapon’s damage die as the superiority die.
