Why is the HID_MAX_USAGES value so low in kernel?

I was wondering why the HID_MAX_USAGES value was still less than 13k, when most gaming mices need 32k or 64k. Values are found in include/linux/hid.h from the kernel sources, and this is still affecting kernels up to 3.10.5

Does Canonical have a good reason NOT to use 64.000 as a value for HID_MAX_USAGES in their kernels ?

Well, I don't have an aswer yet, but kernel 3.11.0 (stable) works great with gaming mices, altough the HID_MAX_USAGES is still on ~13k. So, it's solved, and possessors of gaming mices will no longer need to rebuild the kernel with modified hid.h.
