I've noticed that this one is actually advised as the method to cleanly shut down in one of the "Tip of the day" entries that occasionally pops up on the front page of the website...
Perhaps something to be removed from the pool?
Having refreshed my memory by checking "man halt" it appears that 'halt' invokes 'shutdown' with "appropriate arguments". However whether 'shutdown's "-h" or "-H" argument is that which is "appropriate" is not stated ("-h" halts and/or powers off**, depending on the system, whereas "-H" just halts). Hmmm...
**Of course the Pi cannot "power off" and, IIRC, elsewhere in the forum it has been stated that shutdown/halt causes a partial re-boot to occur and hence the need to wait for the final 8 or 10 flashes of the green ACT led before physically removing power.
Still running Raspbian Jessie on some older Pi's (an A, B1, B2, B+, P2B, 3xP0, P0W) but Stretch on my 2xP3A+, P3B+, P3B, B+, A+ and a B2. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm
