Long since. (-: It was in version 1.0 .

It has. The systemd people were responsible for getting this mechanism
into Linux in the first place.

Now observe it under not init and not htop. (-:
Here's the nosh service manager's subreaper mechanism in action. Process
31427 is a per-user service manager, which is a subreaper. Process 9408
is GNOME Terminal and process 9412 is a Z Shell running connected to
that terminal. In the shell, I ran (sleep 6000&) which resulted in an
orphaned sleep process, process 9451. As you can see, that process has
been reparented to the nearest subreaper.
