Yada yada yada.
The J has limited strip clearances at present thanks to our friends at Kwinty Kwoo down the road. I don't honestly know about side door despatch of meat bombs. They are doing the Falcs but they're off the ramp. They're also doing PTS - I assume that must be off the ramp too if all these horrible rumours are true.....
I would hazard to guess that if the K had been put through the same tests, trials and trivia when it came into service then it too would have had it's clearances delayed but hey ho.
