Yes we only allow one single unique prefix. Whether it's an interwiki or a language link is just a simple bit of meta information on that.

We created this table practically just for the interwiki prefix stuff.

How are our interwiki links supposed to work when foo:Bar can simultaneously point to an interwiki, an intersite, and a sister site, and possibly three different sites at the same time?

Where do you see local site idenitfiers being used besides our interwiki/interlanguage system?
