I see it that way: packed is needed to be sure that at least for struct

It might
work without, but that depends on the compiler (-version, architecture,
whatever).
Have there _ever_ been _any_ combinations of compiler, version,
architecture, whatever, that had unwanted padding bytes in this
structure?
I don't know. But if there would be no doubts, this discussion would not
happen and I assume there never would have been an attribute packed there.
