I've gone through most of my minifigs that are connected to baseplates/plates and about 15% have at least 1 crack in one foot. They still clutch pretty well through, even the ones that have cracks in each foot.
And it's not an age thing either. I've got minifigs that I put on a baseplate 5+ years ago and they're fine, but on the flip side I recently bought a couple of the recent Orc CMFs and put them on a plate and with in about a week one of them had cracks on both its feet.
