"Why" is:

* because all fetch phases that fetch from a version control system do so via a single URL
* I was not aware that you could fetch from multiple URLs in a single "svn checkout" command
* many ports were abusing svn.url to include arbitrary commands; I wanted to put an end to that practice
* changing this would probably make the desired feature of cacheability -- https://trac.macports.org/ticket/16373 -- difficult to implement, so I would not want to change this now.

Why do you need to fetch from multiple URLs?

There is no Tcl or MacPorts command called "svn", so you must mean:

fetch {
    system -W ${workpath} "svn co file:///tmp/repos/test  file:///tmp/repos/quiz"
}

However that would override any caching support we might eventually add to MacPorts, so I would not do that.
