Squid does this to a limited extent today.

If Squid has an exired object cached, then it will give this object to
the client if revalidation fails, even if considered stale.

However, this requires that
a) The object was cached
b) The client did not forcibly bypass the cache by "reload".
c) That the feature actually works. Has not been tested in quite some
