There are less complaints about 2018 model. They didn't really fix it.
If my (non-Apple) laptop is anything to go by, the keyboards with that crappy low-rise design have average life expectancy of one year. The 2018 modification will not get clogged with dust until the end of 2019, at which point people will be complaining about it too.
There definitely isn't the same level of complains on the internet about it.
