Just to play devils advocate on this.... BMW has a very similar rear suspension setup and also calls for replacing these bolts. I’ve never seen anyone replace one or anyone have an issue with failure.
The main issue I see is that it can be pretty hard to get your adjustments perfect on the first torque. Sometimes the eccentrics move, or the angles simply change a bit when everything is tightened. This means your “one time use” bolt is getting torqued again. And keep in mind that these aren’t TTY bolts like a head bolt or LS crank bolt. I believe the main reason for recommending replacement is that the nuts are a locking style.
Do what you’re comfortable with, but there’s a good chance your new fasteners are going to get tightened and loosened a couple times during an alignment procedure. As OCD as I am with my own cars, this is something I’ve never worried about.
