I wouldn't worry about it too much. Vector shown is how you screw on pedals anways give or take 10-20° and the bolt and thread is pretty chonky. Imagine laying your bike flat on the ground, standing on it and trying to yank a pedal clean off, not happening.

The crank arm would worry me slightly more but then only if it's lightweight aluminum built and prone to breaking in half like some of the shimano duramax series. If you're riding proletarian heavy ass cast aluminium block stuff don't worry about it. The bolts can take it, too, again very chonky and those tend to be a PITA to come off if you want them to.
