Indeed, this is a class of genuine bugs.
[...] I know there's been disagreement as to the value of using -u,
that it would report $var problems that we already know about and
can do little to fix.
Not just that -- a user cannot accidentally refer to $vars like she can to probes (there is no equivalent of "probe * {}" like "$*"), so this class is much less interesting.
I still think too much test data is better than too little. We can use the kfail mechnaism if it becomes too annoying.
It will become instantly annoying. If you like, check in two copies of the tests, once with -u (and you might as well instantly mark it kfail), and once without (which should pass).
