Yeah, that's pretty important, just like freewheel threads.
The action of pedaling works to tighten the pedals on the crank.
I'm not really buying that. And I've seen riders stranded because their pedal came loose. You just need to use your 6mm allen wrench on the backside and tighten with force by hand. No need to do anything else, like using a long 15mm wrench.
