FADEC will drop into a safe mode if something falls off. It may restrict the power a bit, but it won't shut down.
Modern car ECUs also have this, calling it a limp home mode. Car rpm gets limited to about 50%.
You could argue that the far superior engine management will result in reduced vibration, so bits are less likely to fall off in the first place.
FADEC and powerful car management systems will even give individual cylinder timing and fuelling control, to optimise power/efficiency/cylinder temp.
While people keep buying replacement Lycs and Contis that paid off their development costs 25 years ago, the makers aren't going to just shell out $m developing something else.
Unless we all start installing diesels and FADEC equiped alternatives, but then the legislators won't let that happen as it might not be safe.
Then again, some people argue that the Mk 1 Escort was a good car
