Something they eventually did by clarifying (in the Clone Wars series) that it was a shortcut through a dangerous gas cloud that allowed a Kessel Run in twelve parsecs. (Canon!)

Shame. It made so much more sense to think he was simply talking out of his behind.

Yeah, I still have an HP scientific calculator that will do angles in grads, though I can't remember ever having used the function.

The Wikipedia link mentions a couple of other metric system sillynesses that I hadn't thought of. First, they define the "gradian" as 1/100th of a quarter circle, thus making it inevitiable to use powers of 2 for half and full circles, while the very common 30 and 60 degree angles become infinitely-repeating decimals. And then they go and change the name of the centigrade temperature scale to avoid conflict with this system that almost nobody uses.

What could possibly go wrong!

In 1958 Albert Eagle proposed replacing π by τ = π/2 to simplify formulas. However, no other authors are known to use τ in this way. Some people use a different value, τ = 6.283185... = 2π, arguing that τ, as the number of radians in one turn or as the ratio of a circle's circumference to its radius rather than its diameter, is more natural than π and simplifies many formulas... However this use of τ has not made its way into mainstream mathematics.
