IMHO, we are _much_ too generous at applying this to almost whatever gets exposed between .c files. I have created something called the "restricted" api for our custom python27.dll where I use different macros (PyAPI_RFUNC, pyAPI_RDATA) to mean that things aren't exported for "restricted" builds. We use it to remove some of the easier access points to the dll for hackers to exploit.
Also, once declared exported this way, things become more bothersome to remove again, since once could always argue that someone out there is using these thigns.
