So it sounds like it would work - and it would probably be a simple

"cannot access the pack with old versions" - but I think it's a really
fragile approach.

So if we ever change the pack format again, it's something to think
about adding, but probably not worth it on its own...

What if we simply have a cache file per pack, which again is generated
when the pack is first received or generated, but is otherwise not
dynamic?  It's an extra file which is icky, but it would keep things
simpler.
