Right, but I'm sure the vast majority of LEAF installations are exposed to
the Internet, not sequestered on some internal network.

Thanks, I hadn't noticed those parameters.  The default values do seem
unreasonably low, if most people are using LEAF on the Internet.

But I guess I don't really agree with the design philosophy in general.  How
many packets on an Internet-facing firewall is the right number to be
considered an "ERROR"?

To me, going to red-light mode just because there are a lot (however you
define "a lot") of denied and rejected packets means that you're crying
wolf, and conditions people not to click on the red light to find out what's
wrong.  I think the "ERROR" case should be saved for when things are
seriously wrong, like the firewall is failing to process packets, or all
rules have been cleared, or things of that nature.

Again, I'm perfectly happy with the use of the yellow light to indicate a
"high" number of denied/rejected packets, just not with the use of the red
light to indicate "even more" of them.
