It is true... to an extent. But lowering your mash temp a half a degree would still have more impact. Palmer & Jamil like to bring that up every once in a while I've noticed.
As for mash thickness, I believe in consistency. There's the set ratio method which I use - I just stick with a 1.4 for everything. Or the Tasty method, where the strike water volume is always the same. It's more about repeatability & knowing your system than using the thickness to try to accomplish something. Pretty much any parameter you are trying to change with a thickness adjustment can be done in another way.
I do like the Tasty method a lot, especially if you're building your water from RO, but on my HERMS system using the same ratio gives me much more benefit with recirc & ramp stability. I forgot why I did that until a few batches ago when I forgot to adjust it on a recipe & ended up with a 2.1. It worked, but it was a pain in the ass getting my HERMS to behave - not because of the actual thickness, but from the variation. If I went to a 2.1 for every batch, I'd be able to dial it in after a few tries.
If I was aiming for something bone dry, pre-HERMS I'd just go for a lower single infusion temp, with HERMS, it's just too simple to do step mashes.
