At the moment, a Main Page in MediaWiki uses the common namespace tab, i.e. "nstab-main" if it's in the main namespace or "nstab-project" if in project namespace. However, the text of it ("page", "article", "project page") is not really correct and should IMO always be replaced with a localization of "Main page". Quite many wikis have already done this, but often in bad ways, for example via JavaScript, which is bad for accessibility and performance or via parser functions in the MediaWiki message, which is bad for caching. Thus, I believe it would be best if the MediaWiki software would provide a different namespace tab for the Main Page by default, for example named "nstab-mainpage".
