I don't think `ABIVersioning` is the right place, since this document isn't really about versioning. (And FWIW I think we need to re-work our ABI versioning story more generally). I'm also not really sure whether we consider our design docs to be user-facing or not. I feel like some are definitely user-facing while others clearly aren't.
