I don't agree, because much of the time you want to both read and write
from a socket, certainly in the dominant client-server paradigm. So you
end up wanting to package up the two ports in a single record, and why
not make that record behave like a port while you are at it?
Note that we ensured in R7RS-small that close-port closes both the input
and the output side of a bidirectional port, even though the small language
provides no ways to create such ports. The presence of close-input-port
and close-output-port permits fine control when that is desirable.
