It's not THAT hard. The problem is that very few people use alternative keyboard layouts. In proprietary software/hardware, there's just not a lot of incentive to satisfy the needs of small minority of users. In the open source world, at least there's the possibility that individuals in these minority communities would be willing to make changes.
