I am not in favor of that, at least not yet, especially I haven't thought about the implications of that on streaming unpacker. I do not have much objections about changing base-delta order, though.

Not really, from my point of view. Probably 70% of motivation of the new \377tOc index format originally came from wanting to have "where is the end of this object" which turned out to be unneeded; and by making repack easier to use I think we do not have to solve 4G issue either.

There is only one case that might need a single pack that can be indexed with 4G offset: initial clone or repack of a huge repository.
