Unfortunately he's right. The hole is there to be locked and tagged. You will have a hard time finding any outlet using a spring loaded ball to retain the plug - they will all use simple spring clips. Further, the operation to punch the holes and the quality issues with aligning the holes means that it's more expensive to have the hole than the teeny amount of metal saved. You know a little too much, please humble yourself. Like, how can you possibly bring up the lockout/tagout for industrial machinery that will never, ever use a NEMA 1 plug for single phase? You can even find name-brand industrial lock-out devices for $6 on Amazon that use the lockout holes to lockout the plug.

Probably like this: https://www.amazon.com/Master-Lock-Lockout-Tagout-Electrical/dp/B001HWF4ME because if you remove one of those with my name on it without going through the proper procedures, you're getting written up and disciplined(and potentially fired) for violating our LOTO policies.
This kind of lock is cheap and easy
