Ah, not quite. Setting private on "default" does cause index to be 
called when fetching "/", but now
default doesn't get called for unknown paths.

To demonstrate the bug, I tried to make a minimal script that still 
showed it. The original script, the one which led me to discover this 
bug, was considerably bigger, and did indeed need / as part of the 
chain. But there's no point in posting the whole, multi-controller beast 
if I can demonstrate the bug with the most basic, two subroutine controller.
