I find it astonishing that they've included it in the replacement program. That gives me no confidence whatsoever, and after having replaced and returned both 2016 and 2017 MBP models, I am going to stay well clear of this keyboard form factor.
I think you can actually interpret this new MacBook Pro's inclusion in the repair program multiple ways. It could mean that they don't have much confidence in the updated keyboard. But it could also mean that they want to reassure customers that they will be taken care of. Kinda like the free bumpers in response to Antennagate: Antennagate wasn't actually a thing, but they gave away free cases to mollify people and just shut the door on the whole issue.
I have no idea which of those is the correct interpretation...
