It would be easier if sites each had an ID, it help with keeping track of them, not only in a numerical way (which is generally easier and smaller than using name strings).

Also changes of site names (such as when a site progresses from beta, or decides it's name is not quite right during beta).

Everything else has IDs so why not sites?
