Just using the 1.11 defaults here on my home wiki, it would be nice if e.g., [[wikipedia:zh:Bla]] would produce a link directly to http://zh.wikipedia.org/wiki/Bla instead of http://en.wikipedia.org/wiki/zh:Bla which yes, gets there, but not as efficiently as catching it in the parser, which perhaps is too overweight as it is, and as such you might close this bug, (which is not the same as Bug 4285.)
Marking this as WONTFIX. wikipedia: is the interwiki prefix, that's what gets resolved. Now, if zh: is a prefix on that wiki, it will redirect upon hitting there. Your local wiki has no way of knowing what a foreign wiki's namespaces/interwiki links point to.
Actually for my wikifamily I truncated all the interwiki tables, so users must now just use trusty good old fashioned URLs.
