Poor choice of words on my part; we've been over why it wouldn't happen (the way it is on SI, at least) a million times.
My actual question was more of a "Will we take a second look at good ways to implement it (perhaps voluntary or some other non-continent-wide method) if it's popular on SI?"
Even if it's not meant to test people's reactions to mortality for other islands, if the game gets big again and a new continent needs to release, this would be a good experiment for that as well. (I know, that's super far off if at all.)
