I don't have an opinion personally because I don't care
about backcompat for what I use QEMU for. From a pure
upstream perspective, given that we don't support anything
beyond the previous stable branch for security fixes we
already don't really expect people to be doing production
work on old upstream releases. So this is a distro
question really and we need input from the people who
package QEMU. Given that for instance Ubuntu LTSes get
5 years of support I would guess that 4 years might be
a little low, but really we should ask the people with
a more informed opinion.
