First confirmed duplicate of the issue. Thanks for posting it and sorry that you're affected. Interesting theory if it relates to the layout - I really hope it doesn't because in that case we're more or less screwed.
I went to the local Apple store today. The guy at the genius bar basically confirmed the issue, wrote some kind of report describing it and recommended me to use the 14-day exchange policy. So I did right away and I'm waiting for a new machine to arrive. Unfortunately, since it's a 16GB RAM version, it's sent from China which is going to take almost two weeks..
I'll report back when I get the replacement, but since it's going to take a while I'd recommend you to go down the same route (unless you feel that you can live with the noise).
Also, I tried to check the keyboards on the laptops in the store but it was difficult due to the noisy environment and I got the impression that only 2017 machines were on display, and the staff couldn't give me a clear answer. Would be great if we could confirm if this is a bigger (layout related) issue.
