I would have preferred separate alphas and mods, but especially considering this is going to run on (mass)drop I understand the current choice.
A lot of people there don't know what kits to buy for their keyboard while 99% of the times asked it's just alphas and mods. This is why they are currently running complete kits for GMK Red Samurai, MT3 /dev/tty and XDA Canvas. Just pick a kit and go.
The current kit setup fits in that line of offering.
