Well to be fair to them, the idea is that the xenon lamps are supposed to last the lifetime of the car, so they don't really plan for them to be quick to replace, in the same way many other components that aren't expected to be changed are also a pain to get to.
More shocking is when you also come across cars with normal bulbs that take major disassembly to change a bulb, there are a few cars from Renault and Peugeot where that is the case.
Changing the side lights on my Impreza doesn't involve too much disassembly, but it does take me 40 minutes every time I do it, as they are a real pain to reach. I thought I'd be clever and replace them with LED ones that would last longer. The first LED failed weeks after fitting it
