I have not had much trouble with doug fir that was kiln dried. but I am not torquing it into a veritas. 1/2" square seems like a lot to shave down. how fine is the grain?
not all drying kilns are operated the same. mistakes are made and sold. I had a unit of spf that was very brittle, and the carpenters blamed the drying on that.
just recently, I remembered reading that wood is often dried to different M.C. depending on where the product is intended to be shipped. ie if you live in a very dry area, your supplier might spec a lower mc to match emc of your area. wood intended for use on the coast or back east is dried not so much as it will just regain. some wood is heated to HT (high temp) specs to sterilize for export. and some, like I found recently at a small local mill, is dehumidifier dried, never going over 120F.
