It's not available in vanilla.
I don't know if it's planned to be merged.

I use Debian, which has just packaged version 208, and hibernate key stopped working after upgrading from 204. Rebuilding systemd with this patch is the only option.

I am the maintainer a TOI user interface for Debian[1] and I recently added systemd support to it[2]
This patch could be a Debian patch to systemd package but it would help all dists that support TOI if it was merged upstream.

I use TOI since 2006 and given its quality, I hope you will accept such a small and simple patch.
