The Jittering will of course not be recorded in anyways there are several ways for now to tackle these problems you already mentioned one of them another is fine adapting the collision colliders and also using high quality physics.
The Problem with the current Physics though is they are pretty non deterministic you never really know what will happen on the end users system in a certain point in time.
A little timing deviation in the users system could let him see another result as what you would expect for now.
Even if you get it stable on your System and even if the user on the other side uses the exact same setup it still is partly system timing dependent what will happen.
Even calling the GUI can influence the Physic Stability and it's final result currently.
Best Example here is always the non deterministic Penis force slip out, call the GUI and the Penis can lose track the next cycle
For Hardcore Animators that's mostly Painful yeah if you can't really predict things that will happen and currently that's a big issue.
But this also exactly what can lead to some very nice chaotic results.
For example even if the Penis Slips out it doesn't mean it will not go back in at a certain force point
There are plugins actually allready who try to force things into a certain direction by Realtime adapting.
