+1. Needs "abstracted out" though, just abstracted by itself doesn't make sense to me. In the way "pulled out into", makes more sense than "pulled into". One involves pulling it out, then putting it into. The other is one step that doesn't induce a clean visual.

Although, we do need to change the word "tiny core", as that isn't true in the strictist sense of the word anymore. Let's use "Built on a concise core" instead, as that is more true to the intention.
