The reversers are not the issue, they retract in a mere second or two.
The liftdump "feature" JetA was talking about, basically commits you to land.
After landing you have to pull a t-handle out and over a stop and drop it back in. That prevents an inadvertent deployment but also prevents a hasty retraction and as JetA pointed out, a 5500 foot strip can be short in a jet if you land long in the first place, wet and with a tailwind it can get real ugly...
I was told, a scenario for a go-around after the lift-dump has been deployed has not been taught in school (yet).
"why did they deploy them in the first place?" someone might ask. Could be a misunderstanding and the pilot flying didn't know that they were deployed on the go-around. There isn't really the time for checklists. Split-second decisions and all odds against you, very sad indeed
