Adding additional columns is a possibility, but I'd say an unlikely
one.  I think it's worth switching (but low priority) to grabbing the
fourth column instead of the last one.  I think parsing the header
to figure out which says 'enabled' shouldn't be necessary.  I may
one day eat my words of course, I'll take a patch that switches to
that.
