Thanks; I like what you wrote here.

Ditto, I changed that, too.

I think that others will follow it, too. But I agree that it is
confusing, since we're fixing a bug that doesn't yet exist. In reality,
I wrote this patch after sending v1, and then reordered its position to
come before the implementation of MIDX bitmaps for that reason.

So in one sense, I prefer it this way because we don't ever introduce
the bug.  But in another sense, it is very jarring to read about an
interaction that has no basis in the code (yet).

I think that the best thing we could do without adding any significant
reordering would be to just call out the situation we're in. I added
this onto the end of the commit message which I think makes things a
little clearer:

    (Note that multi-pack reachability bitmaps have yet to be
    implemented; so in that sense this patch is fixing a bug which does
    not yet exist.  But by having this patch beforehand, we can prevent
    the bug from ever materializing.)

Thanks,
Taylor
