Extensions with no license
I'm not suggesting the two sites are similar or related. I'm asking, from a legal perspective, are the concerns faced by other WMF projects in regards to hosting content with no licensing. Commons is the example that first came to mind, but in general I'm speaking of the issue faced by all the projects WMF hosts - including MW.org.
Not even getting into the topic of should we house it - I'm asking - technically (legally) - are we really able to at all anyway?
Also, I'm not sure what your dig is on the extension in code template. There's no crusade either, lol. This is starting to sound like cabal talk. There are 2-3 new templates being placed in several places. Efforts to help communication with sysadmins I suppose could be seen as a crusade...but I'm still at a lose for why it should be discouraged. :/
Legally? If the source code was posted by the author to the wiki, it can remain on the wiki under whatever licence (GFDL or CC-BY-SA) was in use at the time it was posted.
If you want to move the code elsewhere, then the original license and attribution must be retained. That may mean we have (if not otherwise indicated) bits of programme code under what was intended to be a documentation license - but that's not the same as unlicensed code.
