Even if we all suddenly agreed to one option, a switch for Jessie is
impossible because of upgrades: a system must not become unusable before
init is reloaded on reboot.  Just like kernels, the previous stable
release's init must be enough for daemons, as you can't[1] replace the
running init.

Thus, sysvinit compat must remain at least until after Jessie.

[1]. Technically, on modern Linux you can ptrace init, and thus force it to
exec() something else, but that's obviously not a real option here.
