In my defence, I was not aware that it was a bug. I thought it was
something I was doing wrong. Anyway, I've done as you suggested and
gdbus does indeed return the same response as my program:

DBUS_SESSION_BUS_ADDRESS="tcp:host=localhost,port=8080,family=ipv4"
gdbus introspect --session --dest org.freedesktop.DBus --object-path /
Error connecting: In WaitingForData: unexpected response `REJECTED
EXTERNAL DBUS_COOKIE_SHA1 ANONYMOUS'

I will report this as a bug.
Matt.
