IANAL, but if there is some flexibility here, I would argue that extensions should *not* be considered derivatives. Legally, because extensions do not contain MediaWiki code (beyond using the programming API provided by core classes);
Ah, good! Yeah, programming to a provided and documented API should be fine. (With WordPress, themes and plugins are very much programs running in the same process, etc.)
in practice, because we have many extensions licensed under licenses that are incompatible with GPL,[1] and I don't think we should require people to choose a GPL-compatible licence should they want to write MediaWiki extensions. [1] http://www.mediawiki.org/wiki/Category:MIT_licensed_extensions
