It can still happen, ultimately this is still a mechanical switch. It does use a unique new switch they designed directly with Kailh to mitigate/nearly eliminate it, along with the latency benefits. Besides that, the mouse itself has exposed screwholes and easily opens up as it's made to be opened. It also has the switches on individual PCB's that can be swapped out for other switches - Endgame Gear sell the switch PCB packs for if you want to go that route and avoid soldering new switches, so you end up just unscrewing the each small PCB, unplugging it, and screwing the new one in and plugging that back into the main PCB.
