You've just chosen a different default. I'd argue that most users (i.e.
not developers of the tool or the kernel) actually want to run with a
disk image and graphics. You can type "qemu-kvm harddisk.img" and that's
it. This is clearly superior to something as tedious as "./kvm run -d
harddisk.img --sdl" and I can assure you that a bash alias is really not
a solution for that.

So, as always, which set of command line switches works better for you
depends entirely on your use case.
