Thus, I'm not sure what I am supposed to do.
What are you giving in by putting the full pathname in the build-time
generated sipconfig.py? That entry in the dictionary is used only by
build scripts that want to invoke sip directly; how are you making any
difference for them by exposing the sip binary extension? If it changes
in SIP v5, let it change; when installing sip v5, you will generate a
new siputils.py with the new full pathname on it, whichever it is.
I don't see it as exposing an implementation detail on which users might
accidentally rely; on the contrary, by *not* exposing it, you're making
some users (like sipdistutils.py) rely on the current value (.exe).
