Just a clarification here:
The book says don't do a go-around after the reversers are deployed. BUT, the real world can throw a curve that will cause you to ignore the book (e.g. a large obstacle appears on the runway in front of you).

Short story, 737-200 lands in a snowstorm, deploys the reversers, then a snowplow appears out of the snow. They stow the reversers, firewall the throttles and perform a go-around and miss the snowplow. Unfortunately one of the reversers hadn't completed the stow cycle before liftoff - lack of WoW removed the hydraulic pressure from the T/R circuit, and the aero forces pushed the reverser back to deploy (clam shell style reversers on the 737-100/200 series). Aircraft control could not be maintained at that low altitude/airspeed and they crashed.
So, although the book says don't do it, it has been a design requirement on every subsequent Boeing design that if there was an aborted landing after T/R deployment, the reversers would stow and lock even if air/ground goes 'air' before the stow cycle is completed.

Again, no first hand knowledge, but I suspect Airbus has a similar requirement.
