I dealt with the guys in the shop there all the time. I can't print here what they had to say about the directive. As far as I had heard there were no objective measurements of road costs that were directly attributable to changes in tire pressures. There were a whole lot of maintenance costs that were documented.

yes, lots of problems, and no way to document road costs. however lower pressure does give better traction- I myself never run more than 80 lbs in drive tires, and sometimes drop them to 70

You'll struggle to find a log truck over here without a central tyre inflation system on the drivers. Starting to see them on some tippers as well. For a lot of forestry roads, you simply won't gain traction unless you can drop the air pressure right down low.
Never seen anything on a trailer, though. Doesn't make a whole lotta sense to me.
