Mostly it's a false dichotomy. The changesets are symmetric -- they
are neither forwards or backwards.
The changesets are also just about the perfect unit for minimalizing
the communication costs of commit and "replay --exact".
The changesets in the current archive format are also just about a
perfect transaction log -- compact in size yet also useful for random
access.
Ancillary structures like archive cached revisions (though many other
things are imaginable) enable all kinds of fanciness in
arch_build_revision.
More "exotic" archive storage management is certainly possible -- most
likely just using the changesets as the wire protocol -- the sky's the
limit.
