Good to see more keyboards with this feature. To me, it's less about modding than maintenance. Swapping out switches is still a pain in the ass compared to just switching to another keyboard, but on the other hand, it does mean that if a switch starts to chatter or gets damaged (from spills, tight keycaps, whatever), you can replace it without having to take a soldering iron to the PCB.
As I've said elsewhere, though, I wish they'd socket the LEDs, too (maybe using top mount LEDs rather than surface mount). LED failure seems to be a frequent issue on backlit keyboards, so it'd be nice to be able to replace them with less risk and effort.
