Allow me to disagree. AppCache has atomic guarantees regular http cache doesn't
have, hence providing significant perf boosts in scenarios where only part of
the resources would be cached in the HTTP cache while all of them would be
available in AppCache.

Furthermore, AppCache doesn't require developers being able (or knowing how) to
set HTTP headers. So allowing non-offline apps to use AppCache would also
provide significant perf boost in such situations.

Yes.
