Would it be considered evil if we put the generation number in the
pack, but not consider it part of the formal object (i.e., it would be
just a cache, but one that wouldn't change once the pack was created)?

That would actually be a major change to data structures, and would
require some serious surgery and be hard to support in a
backwards-compatible way (think different git versions accessing the
same repository).

Much bigger patch than the one I did.

So it sounds like it would work - and it would probably be a simple
matter of just incrementing the pack version number if you just say
"cannot access the pack with old versions" - but I think it's a really
fragile approach.
