I think the "feature knob" makes sense. I don't know that it is worth
extensive testing with old releases. You have a pretty good guess about
which versions are affected, and people who experience the problem can
turn the knob. Your Makefile comments make it easy for them find the
knob once they see the breakage.

It is probably worth mentioning in the release notes to give a heads-up,
though.

Thanks.
