Why? :)

QEMU as-is (without source code modifications) has quite a few use cases
beyond KVM - it exists much longer than KVM.
qemu-system-* can be used to test/port userspace software on platforms
you don't have the hardware for, such as different endianness. Kernel
and firmware development may have faster turnaround times than with real
hardware and may be more automation-friendly. Same with source code
modifications for new devices, obviously.
linux-user, in particular qemu-arm, is used for cross-building several
Linux distributions. Scratchbox is another tool-set using it IIRC.
Regards,
Andreas
