ITO, IMHO, I don't think there is a specification in RFC792 or
subsequent that specifies whether or not the "last ACK" in the 3-way
handshake needs to be empty or not, if there is data to send, there is
data to send, however, a lot of these
"not-really-a-standard-but-common" behaviors unfortunately get included
as security filters in firewall products.
