For that to work acpid.service should have a

[Install]
WantedBy=multi-user.target

section which will create the necessary symlink in
/etc/systemd/system/multi-user.target.wants/ when you run systemctl
enable acpid.service.

Since we don't have the necessary tools yet to do that automatically on
package installation, the most simple solution is to just ship the
symlinks in the package for now as is already done for the socket.

Correct, in newer versions systemd-logind will handle various power
related events (suspend-key, power-key, hibernate-key, lid-switch).

Michael, if you want me to review the relevant changes or provide a
patch, just let me know.
