I don't see how it's even practical if you wanted to. It would also
need to support systemd-208 for Fedora 20, and possibly systemd-204
for Fedora 19.
Users must be able to upgrade to Fedora n from Fedora n-2 and n-1, as
they're supported systems still. Arguably users ought to be able to
upgrade out of the most recent EOL'd Fedora, n-3.
It makes me look forward to atomically updated/upgraded stateless
systems so we can avoid these kinds of musical chairs figuring out
nutty layout assembly to make sure updates actually work.
