Your 4th link is an issue very specific to one model year with AT only. Again it was fixed with a simple update.
Your 1200 other hits mostly start with "I have an XXX turbo or tune and have idle issues". Pretty much supports they are a mod and tune related problem. Oh and of course there are the many many "Happens when the A/C is on" which is perfectly normal but some people refuse to understand that.
Idle issues are not common on unmodded cars after the very first batch. If somebody with a tuned car has this issue they need to check the tune not ignore it and say "OH these engines all do that". They don't.

Every twin I've seen experienced some from of brief rough idling dip, even after the "fix".
I will confess I haven't spent as much time with the newer models after 2015, but I have still seen it in every twin I have looked at - including the occasional newer models up to 2018. I haven't personally looked past 19 models.
It also could be because I'm in California - which mostly sells only up to 91 octane. May attribute to a roughly idle. And yes, a tuner should be able to fix it.
