It would actually be sudo shutdown -h now. Otherwise it waits a few minutes for the control rods to drop before it shuts off the coolant control.

That still does stuff like unmounting filesystems (which can take a minute with snap, if they haven't fixed it), you can go further with the (rather unsafe) SysRq key "o", which tells the kernel to shut down without any preparation.
That's quite interesting, considering that -h flag is usually related to showing help.
