"What policy goal does that achieve?" I'm not saying this to be sarcastic at all, but I had the good fortune to have my initial mentor in this business, (more years ago than I care to say) tell me, "Don't try to make sense out of it! Just apply the rules, if there are any. If you try to make sense out of it, you'll make yourself crazy." I thought that was good advice, and I've mostly followed it but I'm crazy anyway. Regardless, I have no good answer for what policy goal this achieves, but thankfully for sleeping at night, I honestly don't care. I'm just thankful that the regulations now clearly spell out a rule, which I can show to recalcitrant clients and their advisors who don't believe me!
