I ask because it seems that dirt and debris is going to be much more of an issue with the new mechanism. My first 2016 13" nonTB MBP had a broken I key (it was only half attached and made a loud pop when pressed) and before I returned it I tried to take it off to see if I could re-seat it. It came off fine but when putting it back on it refused to go on no matter how I tried until just using brute force it bent the plastic piece it clicks into making it so it was never going to go back on. I'm taking extra care to keep they keyboard clean but for now I don't trust myself to take them off and put them back on again if it needs cleaning.
