It was placed there 10+ = years ago to alert users that they needed to upgrade QEMU. At this point, if som= eone files a bug report against a 10+ year old QEMU build, the very first questi= on is going to be if the issue reproduces on a more recent build. The only possi= ble benefit I can think of is for people writing new VMMs from scratch, but any= benefit there is also dubious for a variety of reasons.
