I think that this affectation should be done in getDeploymentSpec which is the dedicated function for this.

I agree. That's where I first looked. But that would mean changing the signature of getDeploymentSpec. I was not sure if that would be OK. But it's an internal function, so changing signature shouldn't be a big deal.

Pushed 4a544b1. PTAL.
