Generalized engineering principles are fine, but real world experience should count for something. See other posts about never having had a chain ring bolt loosen.
Sure, one would expect that most chainring bolts don't loosen under use. That doesn't mean that they are immune from it.
If I told my boss that this fastener will work fine 99% of the time, he'd yell at me.
