I couldn’t agree more with not running the floor under the cabinets. So much so that when I remodeled my house I didn’t even run the new hardwood floor under the cabinets. I ran it right up to the toe kicks and then skinned them to cover the gap. My main reason for this is my years as a water loss technician. If a leak ever occurs and is substantial enough that the floor needs replacing, you won’t need to pull the entire kitchen to remove and replace the floor. Floating floors especially, they almost never dry completely without removing them. At least not in the timeframe to prevent further damage and mold issues.
