Other places have used the notation '#optional' when documenting a
parameter that need not be present on input; although we don't have
anything that strictly requires/enforces that notation.

Should logical-id be 'str' instead of 'int', since we said it is
arbitrary what the guest names its vcpus? Then again, integers can be
made to work (even if the guest OS prefers to name cpus via strings, the
agent can track a 1:1 lookup table between OS string and integer number
handed over qga, perhaps even by returning an invariant pointer address
of the OS string as the integer identifier), so I won't insist.

This returns an error even on an empty input @vcpus, while the docs said
that returning 0 takes priority. But it's so much of a corner case that
I don't care; always returning an error seems fine.
Thus, although there are things you might change if you have to respin
the series for later review comments, I'm perfectly fine leaving this
as-is and you can use:
