Its a minimal drop, hopefully it doesnt upset it much. Surely there is a tolerance in the system? Eibach markets its pro kit to be a direct replacement with no ill effects.

How exactly does esc work? Does it have sensors on the ride height etc?

I thought it just went off the traction at each wheel? When it looses traction it takes action?

ESC continuously compares the driver's steering wheel position to the direction of travel of the vehicle. When the control unit detects a difference, ESC responds by independently applying the brakes to individual wheels. In some cases, it will reduce the engine power as well. Changing the ride height changes the way the sensors detect slide and or instability. If you change the way the car behaves while the system is responding to a slide than chances are the system will make the wrong decision because it’s been programmed to work within fairly tight parameters.
As an example of this FPV deactivated the ESC on all Falcon based cars from BA through to BF11 because they could not afford to ’re-calibrate' the system. Their changes could be described as minimal and yet they chose to delete rather than chance the system making the wrong call due to them changing ride height and wheel/tyre packages. Its fair to say they had the added problems due to brake package changes but the early BA's had a fairly standard brake package so even with that they still declined to use the system that was not calibrated to the changes in suspension settings (including ride height)

BTW, there will be a hundred people tell you they have done it and have had no problems. :
