you cant see the damage untill its years down the road or even 100x of thousands of miles later.
As your turbo sits idle, it gets pushed inward to the center of the turbo putting pressure against the journal bearing. Once a load is applied it spins up faster and the pressure draws it outward away from the journal bearing. Over time, idling the car will prematurely trash the journal bearing and the expensive turbo will need a rebuild or replacement, or worse a runaway could happen.
idling any car with a turbo is a bad idea in this regard.
