Competent designers and engineers consider the risks of incorrect assembly, and depending on risk assessment (probability vs severity of failure), and cost-benefit assessment (cost of redesign vs cost of inspection), and based on that decide on if further mitigations are required.
Generally if it's possible that a complete failure of process happens, designers will plan for that. Anything outside of fully automated assembly processes with interlocks and safety checks warrant that to a decent designer. You cite cost of redesign but we're talking design in the first place. What's on the table in this discussion is design, not response to failures.

Competent designers do think about those things.

Sure that makes sense.
