Yes, you are right, pack and send contiguous deltas works. I wonder
whether to add that split function is worthwhile as mere workaround because
first, as far as I see in the logs during debug, it is not very common to send
more than 2 or 3 deltas at once. Secondly, I think the actual issue is in the
client side (or protocol's message): since each received delta message doesn't
have both start and end version, the deserialize method can't infer the right
ones if they are not contiguous.
