Only supporting a single -P wouldn't be a problem if lxc-autostart was
to be run as the user in question, which it ought to be anyway as you
don't want user-owned unprivileged containers to be spawned by root
anyway.

Though I believe the real answer for auto-start of non-root unprivileged
containers is to have the user make sure "lxc-autostart" is called
whenever they want them started and "lxc-autostart -a -A -s" is called
whenever they should be stopped.
Both those calls are to be done as the user and so will use the default
lxc path for that user (either ~/.local/share/lxc or whatever is
specified in ~/.config/lxc/lxc.conf).
