Whether a page is marked to be indexed by search engines should be indicated at MediaWiki's info action. Determining whether a page is marked to be indexed or not requires checking for NOINDEX, INDEX, and a few configuration variables (which can control index status on a namespace basis).

There may be a function for this already, I don't know. In any case, it would be useful and interesting metadata to include at ?action=info.
