Isn't this why we have the

If a script is setting variables for its own use, there's no need to use
functions from rc.subr -- it can just set the variables directly.  If a
script is editing rc.conf, sending a SIGALRM to $$ will signal /etc/rc to
re-source rc.conf.

I'm really not clear on what this commit accomplishes.
