Well that's pretty much like the traditional shutdown plasmoid with PA look &
feel, isn't it?

Makes sense to me, as you often want to quickly lock the screen because you
need to carry the device around for a few meters.

That's a hardware function anyway, correct?

What about hibernate? It has the advantage of no data loss and faster boot-up
time. The advantage of shutdown though is that if allows for a "clean start".

In a perfect world, that's true. But I don't think we can expect there won't be
bugs that affect the system so badly that even end users will want to reboot
their device. This may be a little more hidden than the other options since it
is only for cases of "emergency", but I'm not convinced that no end user will
ever need it.
