Nobody uses this because the x86 prekernel environment is corrupting the ramdisk image prior to running the actual kernel. In the future we can ensure that the prekernel doesn't corrupt the ramdisk if we want to bring support back. In addition to that, we could just use a RAM based filesystem to load whatever is needed like in Linux, without the need of additional filesystem driver. For the mentioned corruption problem, look at issue #9893.
