The tricky part is that it's possible to change a character name and then quit the client, so we'd need some sort of persistence here. This is a problem we're working on solving, and hopefully in a way that every addon that uses saved vars doesn't have to roll their own upgrade code to handle this (though more complex or non-standard uses will have to). Right now the plan is to add some automatic functionality to ZO_SavedVars:New that can be opted out of.
