I think the main point of modern marketing has more to do with the availability & “normality” of suspension forks, anyone who didn’t grow up in the 90’s think they are the norm & they ride to suit, those of us who have progressed from rigid to suss forks just see gravel bikes as the crap we were riding 25 years ago, or embrace them & use skinny by modern standards 29er tyres ;)
