The Goldsboro crash didn't came "close" to a detonation, the result of the crash were that all but 1 of the fail safes that would prevent it from going off were damaged, it doesn't mean that it would be able to detonate if the last one would have failed too from the crash.
The detonation sequence of the nuke isn't just the conventional explosive part it's also the nuclear trigger itself (a fast neutron source) which has to fire at the exact time and power levels while the casing is still intact and can be used as a neutron reflector.
Without that even if the core goes critical it would not detonate (might result in a fizzle if the core is really big) but it would go very hot and melt down.
"one point safe" is a metric in which the US measures the nuclear explosion due to accidental detonation, anything above 4 lbs of TNT doesn't count as one point safe, this however doesn't mean that any none one point safe weapons can be detonated at full yield or anything close to that.
So yes I would still stand by the fact that there is absolutly "zero" chance of an accidental damage to a weapon to bypass all the PAL's and other failsafes and initiate a nuclear triggering which would result in a substantial yield detonation.
With modern weapons it's even less likely since technically modern designs can be considered "subcritical" (under normal pressures and conditions) and only undergo fission when they are configured properly via boosting/salting and neutron management, this is how you get "dial a yield weapons".
