Ironic that this is the hack that I ripped out (for basically the same reasons)
when I started working on V3.
Unfortunately, I can't actually test it yet to see what problems removing
that old hack will expose (FWIW, it's not my hack, and it pre-dates movement
of everything to public lists, so there's no discussion of why the change
was made).
