SUScheduledUpdateDriver enhancement?

I'm working on my first project that includes Sparkle for updates. The product consists of a launchd daemon, a system preference pane and a LSUIElement user agent application. It turns out that it was easier to write a separate application to manage the update process since I need to use a PKG based installer instead of a "normal app" DMG. I _thought_ everything was working fine when simulating a user click on "check for updates", but then I changed to using the 'checkForUpdatesInBackground' method and things stopped working. I thought it had to do with file permissions, but then I looked at the sources and discovered that the SUScheduledUpdateDriver - (void)didNotFindUpdate method did not call the delegate's updaterDidNotFindUpdate: method. This was causing me trouble because I wanted my updater app to automatically quit if there were no updates.

Anyway, I changed SUScheduledUpdateDriver.m so that - (void)didNotFindUpdate is now implemented:

- (void)didNotFindUpdate
{
 if ([[updater delegate] respondsToSelector:@selector(updaterDidNotFindUpdate:)])
  [[updater delegate] updaterDidNotFindUpdate:updater];
 [self abortUpdate]; // Don't tell the user that no update was found; this was a scheduled update.
}

That solves my problem, but I wonder if it is generally useful to be implemented this way. I thought I throw it out there and see what people think.

Thanks,
