Comment (by flixos90):

 I think we should discuss in detail in a REST API meeting whether
 `register_meta()` should require `default` to always be a `$single` value
 or whether it should dynamically adjust depending on whether `$single` is
 true or false. I'm thinking we need to do the latter because otherwise it
 would be impossible to register an array of default values where `$single`
 is false, which would be a perfectly valid use-case.
