With my CSR Group member hat on ... not sure what you mean by 
"documented" here? The property already exists and should already have 
had a CSR (or old CCC) request when it was added. I don't think allowing 
a new value for that property requires a CSR request, simply an update 
to the documentation of the property. Of course if that documentation is 
part of an API then that itself would need a CSR request - but I don't 
think we document this at the API level.
