Might it be worth restricting rc.conf to be a (very small?) subset
of sh syntax so that it remains both a valid sh script and also
easier to parse in a program?
Clearly things like the end of /etc/defaults/rc.conf would have to
be handled differently, but that might be a good trade off to make
the file more easily parseable in many languages.
