The version with a single repeated field (which presumably you expect to
always have size 16) will be slightly more efficient on the wire and
significantly more efficient in-memory (assuming you're using C++).
I think you'll find the single repeated field version more usable, too --
you can actually iterate through the contents rather than having to identify
the all by name.
