Yes there is a very good reason: I want to know ;) I feel like, figuring out, hacking, contributing, and I am leaning for low level, driver and hardware. I'm not interested in uploading an image and use it. I want to hack. My personal challenge would be to bring the magnetic switch to power on/off the screen automatically with the nexus 5 protection case.
I know it's definitely not a priority for the Ubuntu-touch project (that's why I won't blame anybody if there is no response to my questions), but I have so much to learn on linux, ubuntu and your working process that I won't be effective soon. So I try hard to figure that out, it's very instructive and soon or later I'll push some contributions on your servers.
