Making it editable is still planned, we just haven't got to it yet. Will hopefully have more info on that soon.

Regarding the whitelist in general: it's a little hard to say, because every message can behave differently. We are looking to get more existing messages whitelisted, especially if they are more commonly edited, and we are keeping the whitelist in mind when developing features.
