This feels a lot like the debate about whether Pluto is a planet: what we're really trying to figure out here is whether we can figure out a definition for a concept that includes all the things we think should be included, and excludes all the things we think should be excluded -- and the meta conversation is: can we all agree on what should be included/excluded? That's a bit of a dance, since a cleaner and simpler definition can swing people's opinion about inclusion/exclusion, so the influence goes both ways.
