I was afraid that Windows would be a problem but when I tried it at work getfqdn() returned what I expected. Granted that's on a moderately well administered Windows domain :-/

I agree it isn't very difficult to modify the config.ini and restart the server. Do you feel that more documentation changes are necessary to make it more "obvious"? If you have suggestions for documentation changes, I can make those.

If it is okay as is, this issue should probably be closed.
