I think it all depends on the standard of grazing that horses are on.
I remember when I was a child. Ponies lived out with no rugs, but they were never clipped, because they never lived on cattle grazing with rye grass and clover. They never got mud fever or rain scald because the grazing wasn't over grazed and liming and dung spreading happened. None of ours ever had laminitis, they were worked a lot in the summer, but not a lot in the winter as we were at school.
I blame a lot of these issues on stack em high yards with unsuitable grazing. I look at my current yard with over grazed paddocks that are full of clover and weed and never maintained properly. Yards when I was a child didn't exist. Horses were kept on farms and ground was properly looked after , but sadly things are different these days.
