Even given a whitelist of ports restricted to 80, 8080, and 443 (which 
is a rather drastic whitelist) it's quite inlikely that one would be 
running an HTTP server on all three *and* unable to change the 8080 
server to another port (it's typical to have a eg a modperl backend 
there but not exposed to the world).

You don't need two zillion ports to make it useful, one is enough.

Which is why it can be used for both.
