apparently this is a hack to be able to define proxy autoconfig in the 
location field.

Since it has very restricted capabilities, it's apparently non-issue.

I guess that you can only define FindProxyForURL() this way.

I know of such servers.
And, HTTP proxy does not even have defined own port so people use random 
ports or ports commonly used for this service.

the beautiful nature of HTTP allows us to define port within URL, and 
therefore people tend so use separate ports instead of allocating extra IP 
addresses for proxy usage.

I think Adam Meyer also explained it nicely.

That is FTP through HTTP proxy. Not FTP through FTP proxy.
I repeat, FTP protocol does not support proxies and port 21 would be of low 
usage here.
