I think most of the hookless rims are optimised around a wider tire. So unlikely to be many people running 25mm and hookless. Also depends on road surface - rougher it gets the lower the optimised pressure. I’m a little lighter than you at 80kg and running 28mm tires on hookless rims on roads that are often pretty crappy, and the max tire pressure of 72 just doesn’t concern me at all.
I think the key thing is that by making these hookless compatible Continental have aligned with the ETRTO standard, which regardless of whether you’re using hooked or hookless should mean they fit more consistently on rims from manufacturers who are also aligning with that standard.
