Yeah. My concern on reading Alyssa's patch is that it goes into too much
detail about "why", when this is basically just "it's a bug that nobody
has yet fixed". I think it makes sense to warn people about the
behavior, but we should probably be vague about the reasons and up-front
that there is really no good reason that it doesn't work (and it might
in the future).

Of course fixing the issue is better still. ;)

I've been meaning to come back to this for, oh, going on 8 years now:

  https://public-inbox.org/git/20111110074330.GA27925@sigill.intra.peff.net/

(though it was meant to work with a CDN "try this first then top-off"
strategy; with Jonathan Tan's more flexible CDN work which uses raw
packfiles, I doubt I'd come back to this).
