I was talking about users not heeding our warning, but I'm still not
really that compelled by making the test-helpers an optional component
in our build.

I am pretty sure I have only reached for the test-helpers less than half
a dozen times over the years, and *much* more often find myself in a
debugger. If I'm in the minority (and there really are a lot of
administrators who find it useful to have the test-tools on hand), then
that is a different story, but my guiding assumption is that that isn't
the case.

My point was only that we cannot guarantee that users read or care about
our documentation.

Thanks,
