To avoid wasting a byte. I don't have any use in mind for this byte,
but I think it's good to leave this byte explicitly free for future use.
See this discussion for how the u16 came to be:
https://lists.gnu.org/archive/html/qemu-devel/2016-07/msg04564.html
We could use a bool but in some systems that would take > 1 byte.
