Similar story, 2 keyboard-only replacements and one main logic board + keyboard replacement on a MacBook 12". A week ago it failed again and I'm nowhere near an Apple store so gotta wait it out. It's been about 2 years.l since I bought it for my wife who uses it for light browsing.

I bought a brand new Pro 2019 model but haven't opened it yet and hoping to resell it since Hong Kong doesn't do returns -- where it was purchased. It's keyboard was already listed in the replacement program, even before I bought it. My current Air is 6 years old and chugging along (i7 1.6Ghz with 3.1Ghz boost). The new MBP won't last beyond 4 (Apple support expiry on keyboard replacement).

Not sure how a minor membrane change can help alleviate the keyboard issues. CPU throttling is another known issue. Best to wait it out for the new Air with scissor keys due up later this year.
