Perhaps it was just my bad english mate, it's not my main language and it was the best word I could find to express myself at that moment, what I wanted to say is that if someone is having these issues it doesn't necessary mean that everyone will have them, so far, I can tell that there are software issues and hardware issues:
Hardware - Keyboard still isn't perfect BUT I can't find the pattern that makes it break. The issue with dust getting stuck under the key is solved because even if some of it gets in - much easier to open (without breaking) and membrane does help. Doublestrikes or non-functioning beside mechanism working perfectly - something below, in the membrane construction, and it might be that it's better than before but still not perfect. I'm monitoring that everyday and trying strike/space into notes app almost every day.
Software - Audio glitches, before - really severe, now once an hour or so and barely noticeable (but for me as audio engineer still very important) T2 chip might be the problem but that's not a sure thing.
Kernel panics, personally happened to me only once or twice, never happened after sup update 2, neither on Mojave release (I've never installed any beta software on my mac)
P.S. To all folks, before tellin R.I.P. to ur macbook and going to apple store (this tip is just to help to save some time, do what u want) and getting a new one (that's only for kernel panics) Try to back up your data, make clean install of macos and your software (not just restoring backup) and then merging user data files, can't guarantee anything but I can definitely tell that sometimes updates and some software corrupt the system and it's not fixable with update or smth, so it might be that issue is solved all you need to do is start over and nice and clean.
Peace
