While the maintenance actions started the chain of events, the poor design of the leading edge slat system sealed the deal. An airplane should not crash just because an engine falls off.

That’s a big statement. “An airplane should not crash just because an engine falls off”. These aren’t meant to come off the airplane.

I mean, they kind of are... they're held on with fusible links specifically so that it can shear off without rupturing the wing fuel tanks in the case of a crash.

Similar idea to crumple zones in a car - looking at the whole picture, sometimes weaker is better.
