It actually abuses persistent connections betterer. Proxies can
(under the right conditions) take multiple incoming requests to
the same destination (say, the maps keyhole servers) and serialise
them into a fewer persistent connections.

Besides, it's actually rather cheap to have the first half dozen
layers of the tiles cached. That's what we found - once the users
had browsed most of the globe, the tiles stayed pretty well cached. :)
