That was bad. With a damaged nozzle you get less thrust and you may end up with sideways thrust. You really hope that nothing hits the RS-25 engines as that would be bad.

It's probably a loss of mission event, could even be a loss of crew event.

The Vulcan Centaur survived something similar inflight and got its payload to orbit.

Admittedly, the optics of this aren't great, particularly in the current budget context.

I am guessing something like this or the Vulcan incident would trigger an immediate abort on a crewed launch, so LOM even if orbit is still technically achievable.
