That's right. With the standard implementation I think you will most
commonly hit this if you happen to re-encode a message that contains
unknown fields.
More generally, see
https://developers.google.com/protocol-buffers/docs/encoding#order (short
version: writing fields in order is preferred because parsers may optimize
for this, but writing them out of order is still valid)
