For Translate and Incubator, language can be easily pulled from the title as language codes get used as a page title component (suffix or prefix or some such). However for more general pages this may end up being better defined as metadata tied to the page, which'll need storage and being kept across export/import, delete/undelete, etc.
Note that the North Frisian Wikipedia has a need to identify the dialect for each article (North Frisian is split into roughly 10 dialects which aren't generally mutually intelligible but it may also be hard to tell which particular dialect something is written in from a short stub) and they currently use {{dialect}} templates at the top of the pages to make this identification. There currently aren't proper language tags for the dialects but http://tools.ietf.org/html/draft-hoehrmann-nordfriisk-00 I am working on fixing that.
(I am not sure what that implies for this debate, but it is something to be aware of in the context of page language meta data features.)
