Too many manufacturers of building products would get pissed off. You get to sell more energy. You get to sell more and bigger equipment. Every existing system is now obsolete and now you have to make it bigger. Engineers get to charge more.
Contractors really win.
And you can continue to put the bad stuff in the products and sell them. Of course, no true Southerners were in that meeting. In the South there is more bad stuff in the outside air than there is bad stuff in the inside air. It's the charm of the South.
