Win32 provides named pipes, which are quite similar.

There are some weird issues with blind TCP spoofing on localhost
interfaces using some other interface, I think. In addition, if you
run GnuPG in a multi-user environment (which is going to become more
and more common, although it's of course not the preferred environment
of cryptography to protect personal privacy), all local users can
connect to a localhost socket.
