My actual config file looks a tad bit different, and I agree with you. I was just trying to give an example and I forgot to include what it would take to add a new check - that was my intention, so here it is:

PROCESS = /sshd
MESSAGE = The SSH Daemon has terminated
ALERT = major
[download]

In just a few key strokes, the program now performs one more check and no one even had to open up the code. Of course, I realize that if you want to define a new "type" of check that it has to be coded. One of the other side effects of doing this is having multiple configuration files. Instead of hard coding to "default.ini" - you could use getargs to specify an alternate - as in changing disk space threshold. Each admin could tailor the file to their liking.
