Ping.

This is needed for rocko (assuming systemd with musl is expected to
work with rocko?) so unless there are still strong objections I
recommend merging as-is.

More significant re-work (e.g. preventing systemd-tmpfiles from being
enabled without systemd-sysusers or patching systemd to remove any
dependency on the wheel group) would not be suitable for rocko, so
should be considered separately.
