Sounds like there should be a market for long handled pitch mark repairers. Though a quick Google shows that it already exists, maybe they need some better marketing: https://www.seniorgolfuk.co.uk/ however, looking at the site and the age of the "latest news" tweets, I wonder if they are still in business.Seniors are just golfers whose bad (and good) habits have had more time to become ingrained.
The one thing that I might say is that due to physical infirmity, some struggle to bend over and so the effort of repairing pitch marks is greater and in some cases obviously too much. Many have those ball grabbers on their putters, as they cannot easily bend down, and these tend to damage the edges ogpf the holes if not used very carefully which is often the case.
