I don't see it as a joke. Why not strive for the conceptually cleanest possible conventions?
It's pretty plain to me that tau is more deserving of the status of 'conceptual entity' than pi is. It's the number of radians in a cycle. Practically every time it occurs in physics, pi represents 'half the number of radians in a cycle'. Kind of crufty if you ask me.
