I don't have an issue with folding over, some of the older sockets had quite thin screws and the wire being pushed to one side with only the slightest pressure caused many a hot spot. For the same reason I sit on the fence with twisting conductors together and equally I'd never dream of putting separate ferrules on 2 stranded wires into one terminal.Would that be the same ones that do not see anything wrong with twisting two or more solid conductors together?
Although it`s unlikely anyone would actually class it as an actual defect it nevertheless winds me up to see such things done. I don`t mind seeing light twists of seven stranded etc or even more so of flex to keep it tidy then inserting as one would a solid conductor(s) and yes even then doubling if you feel it appropriate to do (so long as you consider the clamping area under the screw takes the actual pressure and you leave about the same amount either end to avoid crush force to the fold.
