What I was trying to say is that there is no need to introduce another symbol τ as we can simply refer to "the circle constant" as 2π. I am not suggesting to treat 2π as a single symbol in formulas.
The hard part is getting people to agree that 2pi is the true "circle constant" and that pi was a historical accident; once you've gotten over that hurdle agreeing that it should have its own symbol is a no-brainer.
