I've had a Ubuntu laptop for a couple of years now and never noticed
this utility (not that I'd have used it if I had) so it's not all that
surprising to me that it isn't a widespread problem.

Ironically, the very first line of the precmd function defined by
/etc/zsh_command_not_found begins with

   (($?)) && ...

Obviously this implementation predates zsh introducing its own hook for
command-not-found.  It could have been done correctly, though, by the
simple expedient of

   (($? == 127)) && ...
