It does have an upside I like:
It will measure accurately a rim that is warped - because it's measuring circumference to arrive at an ERD estimate.
That's similar to the benefit of a dishing tool - with a dishing tool you don't have to worry so much about axle locknut imperfections or warped axles and the effect they have on flip flop dishing.
