Interesting find by French site MacGeneration. Here’s the article in English, via Google Translate. (Side note: holy shit is Google Translate getting good — this still isn’t quite natural, but there are entire sentences with complex structure and punctuation that read perfectly.)
Here’s the relevant passage from the Apple service document MacGeneration obtained, which was in English:
Keyboard and Keycaps
The keyboard has a membrane under the keycaps to prevent debris
from entering the butterfly mechanism. The procedure for the
replacement has also changed from the previous model. Repair
documentation and service videos will be available when keycaps
parts begin shipping.
This is what I thought all along: the new third-generation keyboard was designed to be quieter and more durable, but Apple, for legal and/or marketing reasons, has decided only to tout that the new design is quieter.
For what it’s worth, I’ve heard from a little birdie or two that my take is correct. Whether this design does make the keyboards more durable and reliable, only time and real-world use will tell. But they were designed to be.
