Does the LP have same recommendations as Hardi: don’t caulk where planks come together and leave a specified sized gap, but where they butt into corners you do caulk?

The caulking should be done by the siding company. It's part of sealing the envelope. It not being done is like a carpenter putting studs in and expecting for the drywall guys to put the nails in for em....in a perfect world of course.

Totally correct. But if they can land a siding job while skating on the caulking, they can save a crap load of time.

But remember a carpenter with a caulk gun can lead to scary things.

Giving a loaded caulking gun to a carpenter is like handing a loaded handgun to a six year old boy with attention deficit hyperactivity disorder - both are horrifying examples of irresponsibility.
