I crashed hard in Missouri on a road crack. Hyperextended an elbow which took a long time to heal.
Crack near a drain in Portland gave a quick pinch flat, and perhaps damaged the wheel.
I think one of the problems with the cracks is that when water gets in, it erodes the soil under the roadbed, and makes the cracks expand.
So, yes, seal them.
We've got a few local cracks that took a lot of sealant, but it is much safer now.
Slippery when wet as others talked about is probably an issue. Ride safe and with caution.
HOT TAR is also an issue in some places, although not necessarily crack sealant.
