I think that package size is a useful gut check about how you're delivering your web app. It's hard to screw up delivering a 100kb package, but it's pretty easy to screw up delivering 5 megs. You can probably also deliver 5 megs in a way that doesn't block anything - but you may not need to devote eng resources to doing that until you reach a certain package size.
