I've seen others use this to set a variable to a default if it is not already 
set, so there's nothing wrong with the approach you are taking.

However, I think it is also true that having some kind of default config which 
lists all values, and then reading a user-changed file containing only the 
things which the user has changed works quite well.  It's also nice when a 
program can (re)generate the "default" defaults (eg "postconf -d")...
