As a crappy workaround I have this: https://github.com/sergiotapia/atom-meteor-packages
But still, I would like this to be a core integration.
I've since switched to RubyMine and WebStorm because I just want something that meshes together for me, I don't want 'javascript fatigue' in my dev tools as well. RubyMine's built in visual studio-like debugger is killer.
