There are also templates that are mainly used to describe other templates, and in some cases they may be used in a main namespace too.

For example, how would one classify the demo template? There's also various "sub templates" that some people make which are used to split code that could be used multiple times (for example, this (see the source if you want to know what it does) and this (it has documentation to explain)). These kind of templates aren't infoboxes, but neither do they match any of the types listed. (both created by me for that particular wiki, but most wiki's tend to have templates like this)

You rightly point out that "non-article" is just too vague and is more like a "this template doesn't match any of the other types"
