Topic on Talk:Core Platform Team/Initiative/Core REST API in MediaWiki/Schema

We have `title` and `key` properties that contradict the design principle to group related things into subobjects.

Also, `key` is not a very self-explonatory key name.

I feel like making something as intrinsic to the page as its title into a sub-object is pretty rough on the developer. I can live with it, but I'm not crazy about it.

Given a choice, I'd rather drop the `key` than make a sub-object.
