I think it will be a pretty sizeable jump (100% growth?). I expect the next 0.8 release will make a lot of noise when they leave Handlebars behind and really ramp up the rendering engine side of things.
Yea, I wouldn't call them big either, but they happen none-the-less. For package developers it can be vital. Sometimes A must be loaded for B. It's mainly a third party javascript issue. The compatibility folder sometimes does the trick, but by contrast the same utility doesn't exist for package developers. It's a larger dependancy management issue not tackled by the current packaging system.
Asset ordering for packages is another important issue I'd like to see rolled out for 1.0.
In terms of growth, who knows, right now it appears to be linear, but I feel a ramp up is coming.
