Everybody, apparently except Intel, has already been doing this for years. It's been a long time since process names such as "7nm" actually reflected a minimum feature size of 7nm, and even if it did differing transistor designs means you can no longer predict transistor size/density from minimum feature size. A much more meaningful way to compare processes across different manufacturers is directly by transistor density, but the "nm" process generation naming tradition is so entrenched that every one is still using it but fudging the number in some sort of attempt to position/align their own processes against those of competitors. Of course it's not just transistor density that matters, but also power usage and speed, and no one number can capture it all
